Many proportional brake controllers have restrictions on how and where they can be mounted in your cab. Even if the limitations on mounting a particular controller are relatively few, you still must find an appropriate place in your cab to install it. Typically, brake controllers are mounted beneath the dash. This is done in part to keep the controller relatively out of the way, though still within reach, and in part because this is usually where your vehicle's brake controller wiring harness is located. But this can make it difficult to reach the manual override on the controller, and it makes it nearly impossible to see the display.

Hopkins InSIGHT Flex-Mount Brake Controller Mounted

With the InSIGHT Flex-Mount brake controller, you are free to customize your cab as you see fit. Mount the Flex-Display unit (1) anywhere you can easily see it. Attach the Flex-Control (2) somewhere within easy reach so that you can activate the manual override and adjust the sensitivity. Install the Smart-Box (3) in an out-of-the-way location - either on the side of your center console or on your kick panel - and forget about it. Then simply connect the display and the control to the Smart-Box unit with the integrated plug-in wiring harnesses.

No more inability to see the brake controller's display. No more having to reach around blindly searching for the controller beneath your dash. No more hitting your knee on an obtrusive unit. Now your vehicle will look the way you want while being outfitted with a brake controller that works the way you want.

Proportional Braking

With a proportional brake controller, you can get heavy-duty emergency braking, general braking, or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow vehicle. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently. So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in the same manner.

As long as the InSIGHT Smart-Box is properly mounted according to the included instructions, it will sense - via an internal inertia sensor - how your tow vehicle brakes. This inertia-based sensor responds to the deceleration of your tow vehicle as you brake by signaling the controller to send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

Power and Sensitivity Adjustment

Getting the braking power you need for your application is simple with the InSIGHT. First, set the overall power so that you can achieve maximum braking without locking up your trailer brakes. This can be done using the plus and minus buttons on the side of the Flex-Control unit.

Hopkins Flex-Control Sensitivity Button

Once you have the overall power set, you can fine-tune the power output by adjusting the sensitivity of the internal sensor. Use the button labeled "S" on the side of the Flex-Control to achieve your desired degree of intensity. There are 7 levels to choose from. The first level offers the least amount of sensitivity, making it ideal for lightweight setups. The heavier your load, the higher you will want to take the sensitivity. At level 7, the sensitivity of the internal sensor is as high as it can go. This level is particularly beneficial if you are towing a heavy load because the intensity required to stop that load may be far greater than that needed to halt your vehicle. Therefore, sending out more initial power to the trailer brakes - and causing them to reach maximum braking faster - allows you to better control the trailer so that it doesn't push your tow vehicle before coming to a complete stop.

Simple, Customizable Installation

Each piece of the InSIGHT can be mounted in multiple locations within your cab so that you can customize installation to suit your needs and preferences. Because all 3 parts connect with the specially designed wiring harnesses, you will have to pay attention to how far apart the pieces are spaced and think about how to run the wiring.

Hopkins Flex-Display Mounts on Dash or Center Console

Affix the Flex-Display to a surface that is within your sight line. This can be your center console, your dash, or somewhere near your instrument panel. Once you've determined the ideal location, attach the display with the included double-sided tape.

Hopkins Flex-Control Mounts on Lower Dash or Center Console

The Flex-Control should be mounted in an easy-to-reach area so that you have fast, simple access to the manual override, as well as to the other controls on the unit. This could be almost anywhere on your dash or center console. The supplied mounting bracket lets you attach the Flex-Control to a curved surface for even more mounting options. The Flex-Control, like the Flex-Display, can be affixed with the included double-sided tape.

The red light on the Flex-Control unit will remain on at all times. This safety feature ensures that you will always be able to find the control, even in the dark.

Hopkins Smart Box Mounts on Kick Panel or Center Console

There are no restrictions on the vertical angle at which the Smart-Box can be mounted, but it does have to be pointed in the direction of travel for the internal accelerometer to properly function. You can mount the Smart-Box on the side of your center console or on your kick panel using either the included double-sided tape or self-tapping screws. If you choose to mount it to your kick panel, make sure that the box does not interfere with your emergency brake pedal.

To connect the Smart-Box to your vehicle, you must either purchase a universal wiring harness to hardwire the box directly into your vehicle or a custom wiring adapter designed to plug into the box and your vehicle. To hardwire the Smart-Box, you must remove the plug at the end of the integrated wiring harness.

Installation Accessories

A vehicle-specific wiring adapter (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the Smart-Box - no hardwiring required.

Note: If a custom brake control wiring adapter is not available for your vehicle, one of the following will be required:

20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications

30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications

Hopkins Plug-In Simple Brake-Control Wiring Adapter - Ford
part number: HM47845

Designed for your vehicle with a factory tow package, this wiring harness plugs into the quick-connect harness located under your dashboard and into your Hopkins Agility, Impulse, Reliance or BrakeForce brake controller for easy installation.


  • Connects your Hopkins brake controller to your vehicle's factory tow package
    • 1 Plug is inserted into the back of your electric brake control
    • 1 Plug is inserted into the factory-installed port under your dashboard
  • Requires no cutting or splicing wires for installation - just plug and play
  • Works with Hopkins Plug-In Simple brake controllers (Agility, Impulse, Reliance and BrakeForce)
  • 90-Day limited warranty

Tech Tip: The OEM plug in your vehicle is located under the dashboard to the right of the steering column, behind the black pocket in the dash.

This brake-control wiring adapter will simplify the installation of your Hopkins electric brake controller. Once the brake controller is installed, the harness then plugs into a port under the dash. Because your vehicle has a factory tow package, all the wires for the brake controller have already been run from the 7-way trailer connector at the back of the truck to the plug under the dash. If your vehicle does not have a factory 7-way, additional wiring will be necessary to complete installation.

Video Transcript for Trailer Brake Controller Installation - 2006 Ford F-150

Toyota-2006, ford-f150. Well be taking a look at installing the Hopkins inside flex mount trailer brake controller. Part number HM47297, with assistance from the universal wiring kit, part number ETBC7 and the tekonsha plugin wire adapter for electric brake controllers, for ford linking in motor vehicles, part number 3035-P. Well also use part number18140 which is going to be the short no draw mount braking kit. This braking control system is for braking parts 246 and e-trailer brake applications. This brake control is inertia activated and when the vehicle is not moving, the brake control will not automatically apply the trailer brakes.

In this event, the manual brake can be depressed to actuate the brakes. This brake controller is designed to operate with trailers with electric and electric hydraulic brakes.Speaker 2: Well first mount our bracket, you can mount it directly to the hedge with the included clamp or like we are doing here, run it behind the bumper. Now we can go ahead and attach our seven port bracket. Using a the provider hardware well slip it through and attach it. We are using eight millimeter socket to tighten it down.

Well go ahead and slide our seven port connector in and itll look about like so. We are going to use the hardware provided to attach this now. Well go ahead and attach that to our factory foot port to make sure everything is working correctly. Well attach that to our running whites, which is going to be that brown wire. Put them off, electronic signal which is going to be that yellow wire, and right turn signal. How about the brake lights Looks like everything is working great.

Well put a little bit of dialectic grease in there and make our connection to our simple harness. Take the seven port far away or well have a little bit more, just to ensure that we have a nice connection thats going to last a longer time. Then well fit the two together, now Im going to take a zip tape and just wrap that around it to secure it and make sure it never comes unconnected unless we want it to. You have plenty of zip tapes in your kit to do so, dont be shy about using them. We are going to have a couple of wires left hanging here; we are going to have a blue, a purple and a white. White is going to be our ground, we are going to anchor that, somewhere solid to the back of the body here to a good grounding point.

The purple, we are going to tuck up because its not going to be used. This could be for reverse lights, we are not going to be using those. Then we are going to have our blue and black. Blue is going to be our wire thats going to connect to our white on a duplex that we are going to use, running up to the blue wire coming up for brake charge. Black is going to be our power, going to our 40amp relay and running to our battery. Both those wires are going to go of course to the front. We are going to this right here, its going to that sheet of metal at the back side of the body for our grounding point. Its going to be a nice flat surface, so itll be easy to drill a self tapping screw into. With that nice and tight, that will be a good ground point for us. Now we are going to take our duplex which is going to be that black and white wire and connect those to the black and blue wire coming off the seven port. Place the black to the black, now the white to the blue, ensure Im in, I want to cut that down as well. Im going to start here at the base or we are just going to work all the way up. Well go ahead and start running our duplex up to the front of the vehicle. Well run it up over the top of this spare tire brackets and cross members, over the rear axle, right up here next to our other lines. Over the top of fuel tank, along the frame rail, coming out on the side of the fuel tank, can you see it here Over the top of the bracket and then we went through the frame to avoid the exhaust. It will come out on the other side, running through the factory clips and up back behind the tire and into wall, up into the engine compartment. You can see our duplex wire coming up to the side of the filter wall and not abstracting anything thats going to moving around, such as your steering shaft right here. We are going to bring it up on the other side of the brake booster to about this point here. At that point well go ahead and split it and remove the cover. Now well take a zip tape and just attach our wires up here at the top, to that wire alone thats existing here in our engine compartment. That we dont have to worry about it falling down and we can let our wires to where they need to go. This black wire is going to run over to the driver side. We went ahead and put a pull wire, halfway back so we can run our black wire over to our battery, because we are going to run that 40amps circuit breaker like we we're saying before and run it to the positive side of the battery. We ran it back behind the plastic here, it has a nice sleek look and its not going to be dangling over the top of the motor. Here is our pull wire, to pull that wire all the way across. Once you have pulled it all the way across you can see you are going to have plenty of excess to do what you need to do. We are going to attach our 40amp circuit breaker to the back of our firewall right here. We have the silver post which is going to take the wire coming in from the seven port at the back, and we are going to have that part at the top. That wire we pulled in from the back, let me go ahead and stretch it over so we can see how long we are going to need to cut it. Take the cutters, cut the wire, and well keep the other piece that we are cutting off. Its going to run to the positive side of the battery. Well unstrap this back, creating that on our ring terminal, clip it down and secure that on the silver post. Then well take that wire that we just cut off, well strip back one end of it, connect our ring terminal and place it back over that caper post. Well run that wire back behind our panel here, grab a hold of it on this side over here, pull it through and stretch it over to the positive side of the battery. Now well go ahead and get our bigger ring terminal to connect to the battery and clip it down, connect it to you terminal, place your nut back on and tighten it down. Once thats nice and tight, well be able to secure those wires. The sharp part, we are going to go ahead and punch through our grommet right here and before we get too far through we are going to around on the other side and see where we are at. You can see our pull wire, locator right here, coming through the firewall grommet and then the pattern. Thats a make for a nice clean installation because we are running that wire right along the side of your dash and control units here. Make sure that you stay clear off the steering shaft, the brake pedal and the gas pedal. If you are going through a really tight spot in your firewall, there is a little trick that works out really well and thats using a good quality tape, wrapping it up and then spraying a little lubricant on it to get it through the hole. Now Ill go ahead and pull the white wire through, grab the end of your pull wire and pull it through. We are going to cut it off and then right to where want it. Now we are going to go ahead and mount our Hopkins control unit, now Ill go ahead and get it straight, hold it in place and screw it in. there we have our box mounted, it should be free of any getting kicked, or beaten up and away from the pedals. Locate your wiring harness. Its going to be right down next to your OBB2. Simply plug it in until it clicks. Now we are going to go ahead and turn this back because this is going to be for your tekansha brake controllers. Since we are putting in the Hopkins and the Hopkins doesnt make the adapter, we are going to go ahead and spice into it and make our connections. Ill go ahead and cut the end off, that would normally go to your tekansha. Now lets go ahead and strip those wires and connect them. To do so, well first start with our factory harness that we are using here. Well connect our white wire to our white wire, now connect our red to our red and our black to our black. With the white wire end, back around the top, back side of the dash here, away from all the pedals and then back away from our emergency brake, assume you are running at the bottom. Youll see that we are going to make our cut right about here. Here we got ourselves a little bit of room but we are not going to need all of it. Well cut the blue wire and then well cut the white wire. We are going to peel off the last sort of bit of tape here, strip back the wires and place our back connector on. This is whats going to send your signal back to your trailer. Now tuck that behind, well be able to make our connection. Ill now be able to run those wires back up and over to our factory plug. Now we are going to prep our two places where we are going to mount our control unit and our visual unit. Up here we are going to mount our visual unit. Well go ahead and clean it off using some alcohol and then well use a double sided tape to mount that up. Then well run our wires down the side back behind our emergency brakes just as we did the rest of our wires and plug them into the back of the control unit, down on the kick pedal. We are going to plug it into the bottom one there and then drape our wires back around as we did the rest of them. Any access we can tuck up is secure behind the dash. Now well go ahead and prep the dash, here on the side where we are going to mount our braking switch. Take our double sided tape once again and place it on the back. That looks like a good spot. We can go on and run the wires back behind the dash, for a nice clean installation. Now well just plug it in, the same way we did the other one in the other ports. Now you can see when we press down our flex control its going to read out the braking power that we are putting towards the trailer. If we just go all the way down, lets say to put full power and you can make your adjustments on the side. If you are looking on top if Im pressing up, on the control panel youll see that maximum, its all going to go down to eighty. If I go all the way up, its putting maximum force towards it all apparently.Now we are through for the review and installation of the Hopkins inside, push mount trailer brake controller, part number HM47297 on our 2006 ford-150.You can find this and everything else right here at etrailer at trailer.com.

The InSIGHT Flex-Mount Trailer Brake Controller installed relatively easily. The hardest part was getting my hands and a pair of pliers up under the dash to connect the red wire to the brake wire. The 2016 Ford Escape SE has tight spaces, and no really good place to mount a one-piece unit. This is ideal as I have placed the display where I can see it, the manual control where I can reach it easily, and the controller where it is not in the way of my feet. The hardest part was in installing the ETBC7 Brake Controller Wiring Kit. I will write that up separately. I have not had the opportunity to tow with this unit yet. However, I hope to do so shortly. I expect this unit to work well. I could only wish Ford would have included a connector and wiring so it would have been more "plug and play." 232496


I like this controller very much. It is providing good service. I have not had any issues with it. I especially like the ability to mount the components where I want them. I can easily reach the manual control and see the display. There was a little learning curve to setting up, but it is working well.

The Insight does everything it needed, except the installers would not look at the video on line to use the factory wiring in my GMC. I believe they used the under dash wiring, but ran a separate wire to power the unit to the battery, because they did not want to find the time to do it with factory under the hood. However, they did wire it correctly, and it works great. I had them put the box in the center area of the tunnel, and the other items as pictured, a little differently than recommended, as I like the slider close to my hand and placed it under the shift lever when in manual/tow mode, I can rest my hand on the shifter and tickle it with my finger. Eight months later I had to replace the double stick tape on the small indicator (living in CA, hot on that dash!) 473961

Product came in a couple days and everything was inclueded. For my application it worked out well as I intend to keep this installed. Everything looks neat and clean to me as I have it installed, see pics. Very simple from start to finish, I'd call this one idiot proof, as I did not mess it up one bit. This is in a 2014 Tundra One note, if you plan on removing display and remote control when not in use there are probably better options out there. I think it would work better if the plug ins for the remote were on one side of the control box and the wiring to the vehicle was on the other side. That way wires would be hidden when not in use and you can easily hook up remote and display on the other side. 162925

I ordered this particular unit because I wanted a hidden brake box since my truck was already equipped with a built in brake box from the factory. Installation of this unit was very simple and straightforward. To hide this unit I put the display screen in a vacant cubby hole in the dash, and put the controller in the empty ash tray compartment. I was pleased with the quality of the brake box and I feel it is well engineered considering it is a 3pc design. Once the box was installed everything works like it should. The only issue I'm having with it is getting the sensitivity adjusted, it seems like sometimes it is way too extreme and other times not sensitive at all. I will adjust my mounting location of the "brain" to see if that helps. Otherwise tow thumbs up! 216890

The Hopkins Insight was so easy to install using the pre made cable for my 2106 RAM 1500. It took me less than 10 minutes once I chose the places to put the display and control and watched the video if the install(that was perfect) . Since I have a 2WD model the space where 4WD control would go made a perfect spot. I was going to have the dealer install the integrated Brake control for 600 bucks until I saw the Hopkins insight. For less than $$$ bucks with the pre made cable and I am happy I went with the Hopkins. 355097

I haven't hooked up the trailer and seen the trailer brake in action yet but I'm going to start by giving it a 5 star review just for the ease of ordering from etrailer and the install. I'll update after using it. etrailer matched the plug-in adapter for the system/my truck so all I had to do was push add to cart. It was also delivered on time. I installed it on my 2017 Chevy Silverado 1500 LT Z71. I have no mechanical/electrical abilities whatsoever and I was able to do the install from start to finish by myself. I ordered this particular system because I did not want the traditional trailer brake that is mounted on the kick panel. I was able to mount the system out of sight when it's not needed, as to not change the appearance of my brand new truck, and there is nothing to bang my shin on! I mounted it with 3M double sided sticky tape (other reviews stated the provided tape didn't stick well) and used zip ties for cable management. The Hopkins InSIGHT Flex-Mount was perfect for what I wanted! 405858

This is the first time I've used any brake controller, but when I bought a 8000lb 31 ft travel trailer I knew I needed one, especially with my half ton 2014 Toyota Tundra. I did my research and decided that this Hopkins InSIGHT Flex-Mount controller was the one I wanted. I liked the idea that all the components are separated. I installed the smart box with the included screws next to the parking brake and I don't even notice it's there unless I get out of my truck to look at it. The flex control and flex display I wired up the side of the dash, where the door seals are and when the door is closed I don't even notice its there. The most important feature for me was that I could disconnect the two flex components when not in use and just leave the smart box, since I don't use it very often. The controller was very easy to use, there is power percentage and sensitivity. I drove slowly and braked to test and adjust. Once I got the settings I liked, I just leave it. I always felt in control of my trailer with this system. Etrailer was a great retailer to purchase from. I researched all the places for which I could buy this controller and etrailer had the best prices and the Toyota adapter I needed. I liked that they had all the links necessary to what I need and what accessories that would fit so I would not have to go searching for it. I would definitely buy this controller and from etrailer again! The only con with the controller is that the included double sided tape was not very sticky, but that might have been because I tried to stick in on a dash they had armor all on it and it kept falling off, when I saw my 2 year old had played with the tape and stuck it on my arm rest, they were stuck good and I have to scrub to get the sticky out. If you plan on removing it when not in use I would suggest getting some velcro tape and use that instead so you can easily take the flex devices off. 139952


Its been a year since Ive had this controller. Ive never taken it out. I wish my Tundra had an integrated controller for the looks, but this product works great for those who dont have one! No issues what so ever!

I love the flexibility this kit provides. Instead of having a knee banger that looks like a distinct add on to the Instrument panel, it was possible to mount the components close together in the center console area, to get excellent functionality and a professional appearance. The smart box fits perfectly to the right side of the shift mechanism underneath the center console. There is a clear line of sight to the display when mounted next to the aux jack and the adjustment control is at your finger tips right underneath the arm rest overhang of the console. Take a look at the pictures. I am very happy how it turned out. 250189


For the last year, I have had a flawless performance of this Hopkins brake controller. The last 8500 mile trip with my pop up camper went to Colorado and Utah. We crossed 12000 ft passes on the continental divide and had no issues whatsoever. I am still very happy with my choice.

Took longer to decide where to mount the display and finger control that it did to actually do the work. Unit works as advertised and has plenty of adjustment to accommodate two axles of brakes on my utility trailer. Highly recommended. 145238


I use the controller and accessories regularly and have had no trouble or problems of any kind?..they just work as they should every time. Can?t ask for more than that. Thanks for making 1st class products available at reasonable prices.

So far the insight has been great. I ordered this unit because of the install options. No bulky tbc at my knees. Install turned out great and it has functioned well so far. I've only pulled with it one time. Installation instructions recommended mounting the brain box on the side of the center console or on the kick panel. Which was not an option for me. I ordered this so i could keep it out of sight. After lots of head scratching I finally found the perfect spot to keep it turned right and out of sight in my fuse panel. 263748

Purchased this brake controller because none of the traditional brake contollers would mount well for my application. I installed this brake contoller in a 2013 Ford E-450 class C motorhome. It took quite a bit of creatively to find a proper mounting location for the main controller unit which the instructions tell you to mount on the driver side kick panel or the center console. this can't happen in an E-450. Your foot will strike the the box when applying the parking brake and the dog house of the E-450 is curved and this location would have required drilling through metal into the engine compartment and spacers to make the unit parrallel up and down pointing forward. I thought the passenger kick panel was the better option, however neither the plug-in simple brake control connector wiring or the brake contoller display and remote switch cables were long enough to reach the passenger kick panel. Hopkins needs to add at least 2' of wire to the skimpy 3' that is provided which would allow the install to go on the passenger kick panel. Neither Hopkins or e-Trailer could help with any alternative suggestions for mounting the control box, probably because no one has installed this in a 2013 E-450 Van even though the product number is listed for this application. Apparently Hopkins engineering does not verify that their unit will actually mount in the suggested locations indicated in the instructions. Important information missing from the instructions, is that the cotroller box MUST be mounted in a way that the wires coming out of the box are facing forward toward the front of the vehicle and that the box must be mounted as near to perpendicular to the floor and as close to parrallel with the side of the vehichle. After tearing into the dash and seeing that the wiring cables were too short to reach the passenger kick panel I came upon the best location for the controller to be mounted. I mounted the box to the left dash side of the glove box wall. Glove box must be removed by removing 6 screws. Close the glove box door and hold up as close to the original opening a possible, hold contoller box against the left wall and line up with a small level. Use an ice pick to mark mounting holes, drill 4 3/16" holes, buy 4 #8x3/4" machine screws and 4 nylon lock nuts. Mount with screw heads inside of glove box left wall. You will have just enough wire if your manual switch is mounted on the lower right driver side of the dash next to the center opening and the display is located on the upper edge of the dash above the pigeon hole left of center. I used exterior 3M double sided tape to mount these two items, not the tape supplied, I don't drill holes in my dash and I want those items to stick. 4 star because of wiring length, instructions, and Hopkins customer service no service. 182705

*Note - the Flex-control will always have a light on, even with the Colorado off. *Note - this kit comes with the Hopkins Universal Brake Control wire adapter. You don't need to order one separately. This Hopkins Insight Flex-mount Brake Controller lived up to my expectations in terms of ease of installation and configurability of the placement of the components. There's no way I wanted a brake controller installed on the bottom of the dash where your knee will bang into it and will act like a weapon if you get into an accident. I've been in a frontal crash - your legs banging into the bottom of the dash can be painful enough without having a brake controller to smack into. First off, you don't need to order the stand-alone harness offered: this kit comes with the same harness. Unfortunately it's not shown in the first picture featured for this product, but you'll see it in other pictures if you scroll through. Toughest part of this job was identifying the wiring for my 2016 Colorado's towing package wiring. The video here on eTrailer (for another EBC) doesn't do a great job of identifying the wires by color, so it took several sources found via Google searches to get it right. Here's the hook up: Colorado's red (12v power) to controller's black wire, Colorado's black (ground - small gauge) to controller's white wire, Colorado's blue (trailer brakes) to controller's blue wire, Colorado's white w/ blue stripe (brake lights - small gauge) to controller's red wire. Next up was figuring out where the components should be. Again, I didn't want the inertia Smart-box mounted on the left kick panel where I might kick it or have to drill into the plastic to mount it. I considered mounting it behind the kick panel, but I couldn't be sure there was enough space for it, so I decided to mount it under the dash, in the correct north/south orientation, on the HVAC blower, using Gorilla double sided tape (based on other reviews I didn't bother using the included double sided tape as people complained it didn't stick well). There's enough wire for the wiring adapter, Flex-display and the Flex-control to reach the Smart-box easily in that location. The wiring adapter comes out from behind the kick panel just by the ODBII outlet, runs tucked up under the dash, and then drops down to plug into the Smart-box. I then ran the wire from the Flex-display through a seam in the plastic panel on the side of the dash where it meets the driver's door (you can push to open the gap), and it hid it very well. The wire running up to the display from the side dash panel I was able to tightly tuck into the panel gaps on the top of the dash. The display is so stable that I haven't put double sided tape on it as planned - it just sits there free. The extra cable I zip tied to the underside of the steering column to keep it out of sight and away from the footwell. For the Flex-controller, I wanted it in easy reach as it has both the setting adjustment buttons on it but in a panic stop situation I wanted to be able to grab it without having to look for it. The best place I came up with was on the face plate of the radio. The only obstacle to over come with that location was the compound curve of the surface you want to tape it to. I overcame that by putting a solid piece of double sided tape on the back of the Flex-control (I didn't use the separate plastic mount that came with it), then cutting smaller pieces of double sided tape, about 1" long each, and putting them on the top and the bottom of the backside of the Flex-control. That effectively filled the gaps of the curved surface, and makes for a very sturdy fitment. I ran the cable in the gap at the bottom of the adjustable portion of the steering column and the fixed portion of the dash. I've tested the components with the 18' car trailer hooked up to the truck, but I haven't had it in motion yet so I can't comment on settings. 370722


I need to request that one of the photos I submitted and potentially some of the text be changed to reflect that the Smart-box component of the setup needs to be installed so that the wires coming out of the Smart-box always face towards the firewall, no matter if it is installed on the kick panel on drivers left or right. I sent an email to Hopkins to ask that question, as it wasnt clear to me from either Hopkins instructions or eTrailers review whether this was the case or not. Hopkins has responded and informed me that the Smart-box needs to be installed so that the wires are coming out of the Smart-box are pointed towards the firewall of the truck.I want to make sure my review doesnt add to that confusion. Id ask that the attached picture be substituted for the original Smart-box install pic I included. Id also like to review my text that I submitted to further make sure that it clarifies the orientation needed for the Smart-box to work properly.Id ask that eTrailer review their documentation for this device in order to make the proper orientation of the Smart-box abundantly clear, as I wasnt able to easily discern that fact, and Ive got to believe others will be similarly confused. Im also going to ask Hopkins to consider putting an arrow on their decal on the Smart-box to indicate the direction of travel the device should be oriented to.

I find this this EBC to be very effective and love the modular placement of the components. It works as advertised, and Ive used the Flex-controller when I was towing going down a hill and the car trailer got a sway to it. Just a quick squeeze of the slider and the trailer settled right down - drama done. Quality piece that is standing the test of time.

I just finished installing the Hopkins Insight brake controller. The car had a factory trailer hitch and wiring which made my job much easier. The big trick was locating the proper information on the wiring harness for the car. I found the location online by visiting a Mercedes-Benz Forum. This unit has three components: The control box, a display head and a manual override which each need a home. Once I connected the four wires to the cables that were already under the dash, I mounted the head on the dash at the left, mounted the control box behind the right side panel (in the image, I showed the cable on purpose to show where I hid the controller) and I placed the manual override controller on the center console. This location I think works just great since my arm is resting there already. Total install time for me was about 2 hrs. It fired right up and I am pretty happy with my choice of controller. Thank you etrailer for all the info on the website. It made my job easier...and now there is a resource for the Mercedes Cable assy for the ML. 489131

by: 98 Durango w Factory Wiring -- LOVE IT03/11/2016

Initially, my only criteria for buying this particular one was the fact that it was designed for modern applications, not a 1970s CB-radio style from the old units. That said, I'm very happy with the easy of use and the performance. So far, I've gone a few hundred miles with an 18 foot car hauler and it has been great! At one point, traffic on the Interstate was completely stopped with little warning. I jammed on my brakes and this little buddy did everything he should. I avoided destroying the BMW in front of me, so that's a few dollars well spent! BRAKING: -------------------------------------------- When I brake normally, I notice the proportional control goes up to about 35 at most. I have mine set to 99, but it feels great and never feels like I'm being pushed or working too hard to brake. INSTALLATION: -------------------------------------------- The toughest part was getting to the factory plug location on my 1998 Durango. I finally found the spot, covered by other wires, and clipped in the provided plug. The main module installed wonderfully behind the kick panel to the left of the driver's feet. I tucked it behind the wire harness in that area and zip-tied the module into place so that it won't come loose or tilt. I'm a big fan of not drilling if possible. I ran the display wire up the trim to the top left of the windshield. It looks great there. I can see it when I need, but it's not in the way when I'm not towing. My remote module is attached where the knee panel meets the column and dashboard. The wire slides between the seams and is covered by a rubber flange. There was an included bracket that appeared you could screw it into the dash, then pop the remote on and off. Again, I wanted to leave no holes so I went with 3M industrial adhesive that I already owned, similar to the stuff that comes with a GPS to mount the black circle to the dash. For a location, it's not the easiest place to grab, but I know where it is. It's completely out of the way when I'm not using it. INCLUDED: -------------------------------------------- I bought the package with the cable made for my truck. For a few extra dollars, it was worth the hassle of trying to crimp wires and deal with another potential point of failure. The cable went straight in both sides and my factory-installed wiring worked without adding a fuse or any other changes. It could not have been much simpler. The box MUST be mounted in a way that the accelerometer (think of how an iPhone knows you're moving it) can sense how hard you're braking. I was lucky that my left kick panel had room for it. I've seen other reviews that were annoyed because they weren't so lucky for location. The box is really very small, not much bigger than a larger iPhone. CAVEATS: -------------------------------------------- Some applications might be wired different, but my factoring trailer wiring on the 1998 Durango gives power to the unit all the time (even when the keys are off). I can see value in this, as you'll have brakes even if the car isn't running. I can't think of too many scenarios where it would matter, but it is what it is. It's possible that other cars are wired with the ignition controlling the power to this. Because of the above wiring caveat, there is a red LED on the insight remote control that never goes off. Car off, parked in driveway, locked, middle-of-the-night... LED still on. It's very dim and never draws enough power to matter. The red dot on the display also stays on always (if there's a trailer connected). I also wasn't aware that pushing the manual brake lever on the insight control would also trigger my Durango's brake lights. I guess that's a good thing. It just surprised me. As I drove down the road, flicking the switch to watch the numbers light up -- the person behind me was watching my brake lights flash constantly hah. ALL IN ALL: -------------------------------------------- I love it. Thanks for taking the time for my wordy review. I will NEVER go back to a CB-radio mount style again after this. It's hidden away and not ugly. Other manufacturers would be wise to use this style. 240604

Review of Hopkins Insight Flex Mount Brake Controller (HBC). Wires from Smart Box were routed to Engine Compartment by removing the rubber grommet in the engine fire being used for the hood release. Since this T&C came with a factory installed trailer hitch and a 7 pin electrical wiring harness, the wiring containing the blue wire had already been routed to the engine compartment of the vehicle with excess blue wire available and wrapped with tape. After passing the excess blue brake wire through the fire wall and then passing the white and black wires from the Smart Box to the Engine Compartment through the same hole, the rubber grommet for the hood release was reinstalled. No new holes were drilled through the firewall. The red wire from the Smart Box was spliced to the cold brake wire under the dash. Under the hood the White Wire was attached to the Negative Battery Terminal. The Black wire was routed to a 20 amp circuit breaker we attached to the side of the engine compartment next to the fuse box. We then routed the black wire to the positive battery cable that was inside the fuse box. Working under the dash is impossible without removing the knee panel. There is an air bag installed at the bottom of this panel, but is not attached to the panel. This application was not particularly hard, but was somewhat time consuming due to the difficulty of access under both the hood and under the dash. I have attempted to outline more of the procedures with the pictures I am attaching hereto. Thanks for all of the assistance I received from Jameson C and etrailer. Francis Esely 135437


This is a great brake controller and it has worked out very well for me. Last summer when the weather temp hit 99 degrees I had to replace the double sided tape with a commercial double sided tape that I obtained at an auto parts store that has worked very well. I would recommend this brake controller for anyone.

Great product for my Acura MDX to tow my Winnebago Micro Minnie. I really like the remote display and the remote manual controller. I can place these 2 pieces exactly where I want them for easy read and easy access with having a large all in 1 unit being mounted and taking up so much dash area space. The main unit mount under the dash on the side kick plate out of the way. Excellent for my application. The performance for braking is progressive and not jerky and I can adjust sensitivity and braking power without having to fumble around trying to find the main controller and taking my eyes off the road to do so. I am very pleased with this product. 646441

My original display had a couple of burned out segments, but as usual etrailer's customer support was quick to get me a replacement. The unit was easy to install. The flexibility of mounting the unit, the control, and the display in different locations is great! I mounted the unit to the kick panel, so I don't have to bump my knee on a break controller when entering or existing my truck. The control was mounted to the dash just within arms reach. And the display was mounted out of the way on the dash next to the pillar. Unfortunately the display is the weak point for this product: The LEDs are too small, too dim, and the mounting bracket just isn't versatile enough. In the end, I just let it sit in the corner on the dash rather than try mounting it. A better display and mount would have gotten this product 5 stars! 636603

My brakes still don't work. However I don't know if it is the brakes or the control that does not work. The manual switch does not stay on it's base well 628741


The easiest way to determine if the problem is the trailer brakes or the brake controller is to try the trailer with a different vehicle or the vehicle with a different trailer. That will make it immediately evident where the problem lies. In addition, heres a link to a help article about troubleshooting trailer braking systems. Please work through the troubleshooting strategies mentioned above, and let us know what you find. The manual switch can be reattached to where you have mounted with some double-sided tape.

Purchased this brake controller about a year ago. The install was pretty simple and the instructions were well written. I installed it on a 2006 Ford F150 and everything just plugged in and the running of the wires was petty easy too. After having several different kinds of brake controllers I find this one to be the best. The fact that it senses the amount of brake you are applying to the tow vehicle to determine the amount of brake to apply to the trailer makes for smooth stops. Great product!! I would recommend this controller to anyone who wants a quality product that works as it should and is easy to install. 588464

I love this brake controller, and honestly can't wait to write a review for it! After a lot of research, I chose the Insight because I like that it gets the display up into my line of sight and the control up where I can reach it without leaning down where I can no longer see the mirrors. The three-part installation makes this possible. The momentum sensor provides just the right amount of braking for each stop. (I found that for my trailer, I have to have the Insight turned up almost all the way for it to provide noticeable braking. It still only registers a 30 (out of 95, I think) on the meter on my hardest stops, and I've detected no hint of lockup on the trailer brakes. Actually, the mechanic who I hired to install it was very skeptical. He said, "You're going to have to get yourself a *real* brake controller!" I told him to make this work. One thing I don't like is that, while I'm braking, if I feel like I need a little stronger braking from the trailer, e.g. going downhill through curves on the highway, if I try to manually override the controller using the slider, it starts over again at 0 as soon as I touch it, effectively releasing the brakes until I've squeezed hard enough to apply them back where they were. It's uncommon, and I've learned just not to bother unless it's an emergency. I have since replaced my tow vehicle and ended up with one that has a Draw-Tite 5535 brake controller and I absolutely hate it. It somehow manages to be both grabby and not very effective. Has so few and such coarse settings that I always have either too much braking or not enough. And since it's just based on the brake lights coming on, it's effectively binary. It's also in my way and bangs my leg every time I get in and out of the truck. Hate. It! Miss my Insight and looking to go back to this. Don't listen to my mechanic! Get the Insight! (There may be other good brake controllers out there, but this is at least one of them.) 583063

The controller works ok but the display starting messing up about a month later. Also, the adhesive for the manual control doesn’t last through the summer heat. Honestly if I was doing it again I wouldn’t buy this one. I’d get the P3 instead. 576312


In many cases, powering down the controller by unplugging it from the vehicle for a few minutes, then plugging it back in will solve the display issue. If it isnt, the controller is faulty and would need to be replaced.

I installed this in my 2015 Jeep Wrangler JK Rubicon. It works perfectly with my trailer and is easily adjusted to fine-tune the sensitivity and percentage of braking action. I will say that the instructions leave a you a little bit short though. There are a number of places both here and elsewhere on the web that tell you that the Smart Box can be mounted in numerous positions. I found this to be false. The only “correct” way is to have the SmartBox mounted on its side with the wires coming out of it faced forward and forward “only”... To mount it in any other position will cause the Intertial System to malfunction. This system is required for automatic and proportionate braking of the trailer. The only other thing I would put on my wish list would be for a longer wiring harness for the remote activation switch. I mounted mine on the console by the parking brake lever and barely had enough cable to get to the smart box mounted up under my dash to the left of the steering column. If I had mounted the Smart Box to the kick panel as the instructions suggest, I would have had to mount the remote activation switch in a far more inconvenient location. etrailer - Please review and modify the instructions / videos for this unit.. 529660


According to Hopkins, who manufactures the brake controller, the smart box needs to be mounted so that its pointed in the direction of travel. Other than that caveat, the angle at which the box is mounted doesnt matter. We dont manufacture the controller, but I will pass along your concerns to Hopkins.

  • If your 7-way's brake controller circuit shows 13.9 volts when you apply your controller manual override, but the voltage reading at the brakes is only 9.9 volts then you do have some issue with your wiring. A minor voltage drop is normal but losing 4 volts tends to suggest you have one or more wiring issues. You can check the condition of the contacts in your trailer's male 7-way plug to see if there is corrosion or a bent pin. Trace the wiring all the way to the brake assemblies, looking

  • Will Hopkins InSIGHT Flex-Mount Trailer Brake Controller Fit a 2014 Toyota Tundra
  • Yes, you can use the Hopkins InSIGHT brake controller, # HM47297, with your 2014 Toyota Tundra. If your Tundra came with a factory installed 7-Way trailer connector you will also need wiring harness # HM47815 which plugs into the factory brake controller connector on your Tundra. The factory brake controller plug on your Tundra is normally located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal. But it could also be behind

  • Can the Hopkins Insight Brake Controller Install in a 2016 Toyota Tacoma Under Seat
  • There are no restrictions on the vertical angle at which the Smart-Box of the Hopkins Insight # HM47297 can be mounted, but it does have to be pointed in the direction of travel for the internal accelerometer to properly function. So yes you could mount it flat under your seat as long as it's facing forward. The correct install harness for the controller to install it in your 2016 Toyota Tacoma is the part # HM47815.

  • Troubleshooting Display Readings on Hopkins InSIGHT Trailer Brake Controller
  • I spoke with my contact at Hopkins regarding the InSIGHT Flex-Mount Trailer Brake Controller # HM47297 referenced in your question. The red light you mentioned first coming on when the trailer is connected is simply an indication from the controller that it is detecting the trailer. The numbers that display on the controller both when using the manual switch and pressing down on the brake pedal will show the power that is being sent to the trailer brakes. Since you are testing the

  • Does Hopkins InSIGHT Brake Controller have Manual Override and Light Vehicle Brake Lights
  • If you disconnect power to the Hopkins InSIGHT Flex-Mount Trailer Brake Controller # HM47297 it will cause the brake controller to loose its memory and will require resetting. I spoke to my contact at Hopkins about current draw in idle/standby mode if the brake controller is wired so that it has constant battery power. His response was there is very little, if any, current draw, a few milliamps. He said he has used this brake controller in his van and has never had an issue with the

  • Should the InSIGHT Trailer Brake Controller Light Up with No Trailer Connected
  • It depends on the brake controller. If you have the Hopkins InSIGHT # HM47297 the manual override portion will be lit up with or without a trailer connected. But the numbers display that shows how much power is going back to the trailer brakes should only light up when a trailer is connected. I bench tested one to confirm. If the display is showing power output with no trailer connected that is an indication of a short. The likely cause is a dirty or corroded trailer connector. Clean

  • Troubleshooting Trailer Brake Controller Installation on 2008 Sierra 1500
  • The Hopkins InSIGHT Flex-Mount Trailer Brake Controller # HM47297 is a great brake controller and I'm glad the video was helpful. The orange wire being connected to something in your truck is actually the center high mount stop light, and isn't an issue as that isn't utilized for this application. Having the two red wires under your fuse cover connected to the same left side terminal is most likely your issue with the trailer brake controller not working. These terminals are separate

  • What Position Must the Box of the Hopkins Insight Brake Controller Mount
  • Sounds like the box of your Hopkins Controller part # HM47297 is mounted properly. As long as the controller isn't tilted at an angle and is perpendicular to the ground when installed it can be installed with the wires of the box facing any direction. I know that is somewhat difficult to visualize, but if you check out the review video for this controller our demo guy shows you what this means at the 1:30 mark of the video.

  • Parts Needed to Install Hopkins Insight Brake Controller in a 2016 Toyota RAV4 Hybrid
  • You will need to start with a 4-way (if you do not have one) to install the Hopkins Insight # HM47297 in your 2016 Toyota Rav4 Hybrid. For that you would want the # 118578. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well.

  • Adding a 7-Way Trailer Connector and Brake Controller to a 2007 Chrysler Pacifica
  • To add a 7-Way trailer connector and brake controller to your 2007 Chrysler Pacifica you will start by installing a 4-Way harness # 118303. Then to add the 7-Way and the wiring for the brake controller you will need # ETBC7. I have included some links that show and explain the ETBC7 installation for you. There isn't a brake controller harness specifically for your Pacifica so the controller, # HM47297, will need to be hardwired in. The ETBC7 comes with the parts needed to do this.

  • Recommended Brake Controller for 2013 Ford F-150
  • There are no aftermarket brake controllers designed to mount in the OEM slot. However, I recommend going with the Hopkins InSIGHT Flex-Mount Trailer Brake Controller, # HM47297. It can be mounted anywhere on the lower part of your dash, so while it won't fit into the OEM location, it can be positioned near it or over it. This particular controller uses two small components that are especially unobtrusive. I also recommend using the Hopkins Plug-In Simple Brake-Control Wiring Adapter

  • Installing Brake Controller And Wiring Harness On 2015 Ford Flex Without Factory Tow Package
  • I have attached a drawing that shows how the wires are run for the # ETBC7 and brake controller wiring. There is no plug-in adapter available for a brake controller for your Flex with no factory towing package so it will be a hardwire installation. I called my contact at Tekonsha and they said the plug you sent the photo of is not the connector used for a brake controller. You will need to use the circuit tester that came with the # ETBC7 to test the wires on your Flex. The red wire

  • Which Brake Controller Should I use on a 2005 Chevrolet Tahoe with Factory Trailer Connector
  • The part you were looking at includes the harness for Ford vehicles. If you want to use the Hopkins Agility, the part number you would need is # HM47294 and # 47795.

I would strongly encourage you to get the Tekonsha Prodigy, part # 90885 and adapter part # 3015-P. It is our best selling brake controller and is one of

  • Fuse Location for Brake Controller on a 2005 Chevy Tahoe
  • On your 2005 Chevy Tahoe, if using a Hopkins brake controller you would need connector # HM47795. If it is a Draw-Tite, Reese, or Tekonsha harness you would use # 3015-P. For a Curt controller you would use # C51352. For a Hayes controller you would need # HA81780-HBC. None of these harnesses come with a fuse. It is possible that you are referring to the factory brake controller wiring harness that is included with some vehicles. If that is the case then the fuse for the brake controller

  • 2008 Ford F-250 Will Not Start or Crank After Installing Hopkins Brake Controller
  • First let's make sure you are using the proper brake controller wiring harness for your 2008 Ford F-250. For a Hopkins brake controller you should be using # HM47855. It would not hurt to make sure that it is also plugged into the correct plug on your truck. I am fairly certain there is only one though but it never hurts to make sure. If your truck came with a brake controller pigtail from Ford and you hardwired the controller to it then the wire colors would not match up between the
