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. Just set the initial power level, select a boost setting, and you're good to go.

As long as the Primus IQ controller is properly mounted and is pointed in the direction of travel, 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 Boost for Heavy-Duty Towing

Aside from smoother, more efficient braking, Tekonsha's Primus IQ brake controller also offers a boost feature that gives you more initial braking power for those times when you're towing heavy loads. You can switch boost levels so that the power output to your trailer brakes automatically starts out at either 13 percent or 25 percent of the predetermined power setting.

So, if you boost the initial power so that your trailer brakes activate with 25 percent of the overall intensity at the start, the brakes will reach maximum braking faster. This 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.

If your trailer weighs less than your tow vehicle, no boost is needed. But if you wish to set the boost so that your trailer leads the braking of your towing setup, you can select level B1. The following table gives an indication of when you might use the different boost levels and the power increases that they offer.

Approximate Gross Trailer WeightBoost LevelIncrease in Initial Power Output
Less than tow vehicle GVWB113%
Equal to tow vehicle GVWB1 or B213% or 25%
Up to 25% more than tow vehicle GVWB2 or B3*25%
Up to 40% more than tow vehicle GVWB3*25%

*Both B2 and B3 offer a 25-percent boost in initial power. But the braking curve for B3 is more aggressive than that of B2. This means that, even though you will start out with the same intensity when using these boost levels, you will get an overall more aggressive braking experience with the higher level. So if you use B3, you will reach maximum braking sooner than if you use B2.

Safety Features

The Primus IQ offers advanced safety features to prevent damage to various components of your towing setup. For example, when it is not in use, this brake controller will be in power-saving mode. In this setting, the power draw falls to minimize drain on your vehicle's battery.

When you stop at red lights, or any time that your truck and trailer are at a standstill with the brakes applied for more than 5 seconds, the Primus IQ's "hold" feature will activate. When this happens, the power output to your trailer's brakes will be reduced to just 25 percent of the preset power setting so that the brakes will not overheat.

If ever there is a time that you need to brake your trailer separately from your tow vehicle - when traveling down a steep incline, for example - the manual override is easily accessible. Pushing this slide bar engages the brakes on your trailer with full power. In addition, when you activate this override, the brake lights on your trailer will illuminate, properly warning those behind you of the braking action of your rig.

In addition to all of those safety features listed above, the Primus IQ offers diagnostics such as:

  • Open ground
  • Overload
  • Output short
  • Faulty mounting
  • Power loss
  • No trailer connection

Automatic Leveling and Simple Installation

The self-leveling feature of the Primus IQ ensures that the brake controller continues to function even as you drive up steep hills or through the mountains. Simply mount it in your cab at a vertical angle that is between 0 degrees (level) and 90 degrees, and the controller will level itself automatically.

Correct Primus mounting90-Degree Primus mounting

Note: The Primus IQ must be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function properly.

Installation is a snap. After mounting the Primus IQ unit in your cab using the included bracket, hardwire one end of the included pigtail harness directly into your vehicle. The other end plugs into the brake controller. To transfer the Primus IQ to another vehicle or to remove it for storage, just unplug the unit and snap it out of the bracket.

Installation Accessories

For even easier installation, 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 controller - 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

See also's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle.

Installation of Tekonsha Brake Controller Adapter

Brake-Control Adapter Port

This adapter plugs into the built-in connector beneath your vehicle's dashboard. To access this connector, first locate the instrument cluster finish panel in the center of you dash, near the driver's side. Carefully pry the panel out and undo the locking tabs to remove the panel. Plug the adaptor into the mating connector in the large gray housing behind the panel.

To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.

This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

This will be more of an overall etrailer review as opposed to a specific product review as I've yet to actually test the product. So, you might ask, how can I feel confident enough to review a company whose product I have not tested. The answer is simple and solid...I, in all actuality, tested the very fabric of etrailer itself; their employees (specifically Bill and Kristin, my many kudos to you both). I tested their patience. I tested their gumption. I tested their resilience. I even tested the very foundation of their courtesy. With my innocently incessant questions, concerns and over-dramatizations, I pulled, tugged and prodded at the very essence of, what I can only assume is, their corporate ethic. I begged, probed and, most likely to some extent, annoyed their customer service with email after email for days; although, I'm sure to them it must have seemed like an eternity of overtime. Not once, was a single one of my inquiries met with even the slightest hint of aggravation or delay. If you think that I'm just touting because I love talking, you're sadly mistaken. Never in my long years have I ever "reviewed" anyone or anything online. I don't Facebook. I don't Twitter. I don't even go to the customer service desk at the grocery store. It's not my style and it probably never will be. But, I would feel remiss if I let this one go. There is a reason why their site comes up so frequently when searching for answers to new questions and available products...their company is clearly founded on successful ideals and, every effort of their service department proves it beyond a doubt. In the end, this old man was wrong. And, I suffered them through an unnecessary ordeal. But, I've come to find, that, in life, we get tested, often when we least expect and even more frequently, without knowing why. I can not say that there is a better reason for the tribulation they so positively endured other than to give me the confidence to proceed. But, then again, as customer's, is that not but what we seek. I sought affirmation and reassurance that I wasn't just shoving my money into a machine but, instead, shaking hands with an old friend. I was not disappointed. And, I doubt that you would be either. In fact, in my humble opinion, I believe that you'd have to be downright incorrigible to meet any dissatisfaction with their service. In an online generation where almost every site has almost every thing, and all at pretty much the same price, I can see no excusable reason to overlook the absolute value of total confidence in your purchase. The fact is, that at some point, I will need to order something for or have a question about my RV again, and every time my browser search shows results from, I will go their first because I have the experience to know that they know that the way they treat me will bring me back. 474860

Shipping was great. Stared at it for a couple of days before unpacking. The trailer connector mounting was easy with the holes almost matching the existing holes on my 2013 Toyota Highlander. The first four wires are a snap, they are just plugged into the existing four pin connector. I routed the two wire cable towards the front using ty wraps and improvised L brackets fixed to existing chassis screws. I mounted the Circuit Breakers on the inside of the left fender making sure there was hood clearance (see photo). Then I hit a snag. There was no easy way to get the brake and 12V power wire to the brake controller inside the car. For grins, I goggled "brake controller video" for my car and came up with a video made by "eTrailer." (Thank you eTrailer) Three things from the video helped me: wire access from inside the car through the firewall, a place to mount the controller and how to locate the brake wire. After the installation I had 18" of two wire cable left over. The install took me about six hours. (I'm 71 and I took my time.) A couple days later I connected the trailer for a test ride. The brake controller worked like a dream. Things I liked: Retaining the four wire trailer plug setup next to the seven wire trailer plug. Controller display works but you don't have to look at it. The two wire cable was adequate for the job. Being an Engineer (retired) I worry about things like that. Thing I didn't like: The mounting plate for the trailer plug is a little weak. A stiffer plate would have been better suited for me. and, oh yeh, somebody else to install it. ;=) 135250

I have installed the Tekonsha Primus IQ Brake Controller with the ETBC7 Brake Controller wiring kit on my 1990 Chevy Blazer Scottsdale. Everything that I needed was included and the installation instructions were simple. We will be trying it out for the first time in early November when we are going to rent a small travel trailer. If we like the experience we may buy a travel trailer to go with our brake controller! Before and after pictures attached. Thanks for the quick service and support. 228964


Brakes work perfectly. Our rental trailer worked out great for an 800 mile round trip and 4 nights at a Florida State Park. We bought a used 20 travel trailer in February and have taken it on two short trips and a month long vacation. We have had no problems at all and now have almost 3000 miles of towing behind us. One emergency stop was exciting, but the rig stayed perfectly straight and probably stopped shorter than the Blazer would have done without the 4 extra brakes behind it. Thanks for all of your help and support.

THANKS for the Brake Controller unit from ETrailer. It arrived w/in 5 days from your MO location to my So CAL residence. Even as an Engineer/Scientist from the Delta IV rocket program and no experience with brake controllers, I was able to install this unit by myself. Your continued (live human) support and online video clips proved to be the key elements to this installation...without my symbolic pocket protector. I have attached a few images of the unit, mounted to the fuse-panel cover (3/16 attachments with locking hex nuts) in a 2006 Toyota 4Runner SR5 (with factory tow package). The placement of the unit onto the panel cover allows a new panel cover (no holes drilled) to be used when it is time to sell the vehicle. 85308


Thanks Patrick for the follow-up. The brake controller, for the camp trailer, installation went relatively easy and operation of the unit continues to be great. More importantly is your product follow-up for Customer Service...providing a r-e-a-l name vs. Customer Service dept. along with a phone number and email contact information all pretty rare in todays environment. E-Trailer continues to be my first-source for product information search.

I realy do not know where to start. 1) products and service were prompt and very curtious, but there was a major problem. 2005 tundra trailor hitch, break controller and wire harness. I first ordered and installed a trailor hitch on my truck. I needed the hitch for a tundra that had the drop down bumper with trailor ball holes drilled. Everything went as advertised. However it was necessary to use clips to pull the hitch to the frame to drill the aditional holes. 2. Here is the however. Before ordering a wire harness and controller I read the instructions on your web sight to determen if I had a tow package. I looked for the white plug behind and above and on the left side of the instrument panel to determine if I had a tow package. No white plug could be found. In all of my conversations with sells and letters to techneshions I said I had a 4 pin plug but no 7 pin plug. I had the step bumper with trailor ball mount holes but no white plug. Every one determined that with no white plug I did not have a tow package imstalled. I order a controller and the wire harness. I mounted the seven / four pin harness and the wireing from the rear of the truck to the engine compartment and mounted the fuses. The next day I removed the instrument panel lower trim and the air duct and begin to look for the wiring harness and the grommet in the left side of the firewall to rout the wireing into the cab. I looked and felt around the wire bundles and felt the white plug taped with black electric tape on the outside of the wire bundle. It was impossible to see the white plug even with the trim panel and air duct removed and black tape installed over it. After looking at other web sights I learned that if I had taken the VIN number to the parts department of the Toyota dealer I ould have learned that I had a tow package. If I had known that I had the tow package I would have ordered the upgraded brake controller with the less expensive wire harness. Johnnie Reaves 335964

Installed quickly an easily into my 2009 GMC Sierra 2500HD by wiring up to the factory harness. Be sure to watch the video to see which wires need connected at the fuse box in the engine compartment! (Easy hook-ups, just need to make sure you see which ones get hooked up and where.) And if you don't use your ash tray, these brake controllers squeeze nicely into the ash tray compartment/recess in the lower part of the dash. Makes a great place to keep most of the controller out of the way and it's easy to install (you will have to create 2x new holes in the plastic detachable controller mounting bracket but its very easy - you can see the mounting screws in the 'new' holes and the old holes go unused as shown in the photo). Only had a trailer hooked up once, but the controller functioned as designed. I think the 'Boost' function will come in handy if I use a well-loaded trailer and need some additional stopping power from the trailer. 135875

2010 Ford F-150

Easy install on my 2010 F 150 XLT. There are 2 possible locations for the trailer wiring harness if your vehicle did not come equipped with the mfg brake control. Consult owners manual. My harness was located below steering colum behind lower dash. I routed my harness to the left side behind the parking brake release lever. You may have to remove the outer sleeve of the factory harness depening on your vehicle. Mounted the mounting bracket with double sided foam tape and predrilled holes before screwing in place. Mounted the Pod brake control and tested. 5 stars! 557183

We own a 2015 Ford F150 SuperCrew, 3.5 EcoBoost with Max Tow package. Of course, equipped like this, the truck came with a factory-installed, integral brake controller. That's good news. The bad news is that there various internet forums report there to be an unusually high failure rate of these factory controllers. So, being a bit paranoid about being out in the middle-of-nowhere in our truck and travel trailer and suddenly having (a) locked brakes, or (b) no brakes at all, I decided to install a high quality aftermarket controller. Based on company reputation and prior experience with Tekonsha products, I selected the P3 and proper 'plug and play' wiring harness. Following Tekonsha's instructions as well as vehicle-specific on-line videos, I found the installation to be super easy. I elected NOT to take the truck to the Ford dealer to have the computer re-flashed for the absence of the factory controller. Now, each time the truck is started, I have to click "OK" to clear the 'TRAILER BRAKE FAULT" message... to me that's no big deal. Also, when compared side-by-side, the Ford controller seems flimsy and cheap, whereas the P3 has a quality feel, fit and finish. Wanting the controller to be easy to see and easy to reach, I chose to install the P3 on top of the dash. So, I am delighted with the Tekonsha P3 and - as always - with etrailer's service. 402275

IT WORKED PERFECTLY. This is my first time to purchase, install, and use a brake controller. Add to top it off, it was my first time to pull a trailer. It was on a Saturday, exactly six days before a scheduled tent-camping trip, when my wife found a good deal on a used pop up camper. The camper was equipped with electric brakes, so it was required to install a brake controller on my SUV. It was Sunday (next day) when I ordered the Tekonsha TK90160, along with the other necessary part numbers #118449, #A0500, #18136, #ETBC7. I was planning to take the parts to a shop to have it installed as soon as I received them. I was hoping I can get them on Tuesday, but UPS dropped it off to the local post office, which caused it to be delivered at 3pm on Wednesday afternoon. The shops that I went to either did not have an installer available, or were all booked for the week. I had to "take courage" and install it myself. I am so thankful that provides extensive videos of reviews, installation, and operation of the products that they sell. I made the connections as shown and hoped for the best. I picked up the camper on Thursday, and was sooo relieved that it worked perfectly. We took off on Friday and the camping trip was a success. We are looking forward to making more good memories with our camper. Thank you etrailer! 276385

Primus Iq Brake Controller installed in a Mercedes Benz 2017 Sprinter. The van's electronics interface with the Primus, and it can detect when the trailer brakes lock-up, which lights an dashboard indicator lamp. I used the Mercedes-specific plugs under the driver's seat and ran the cables through the battery box to the dashboard. 489003

This is a great controller, recommended by my trailer manufacturer. I actually don't know too much about it, how it works, etc. But it doesn't require much knowledge to use it. Install it like instructed by etrailer it just works. You can see the number goes up as you apply more pressure on the brake pedal, and the trailer stops with no problem. It's magic. The only thing I wished they do is to supply a longer length of the thin wire to connect to the break line. For my 2013 CRV, the break line you need to tap into is on the left side of the steering column, if you want to install the break controller on the right side, the wire is a little so short; but you can make it, it's just a little tight. I want to install the break controller to the right side of the steering column because I don't want to accidentally bump into it every time I get in and out of the car. It's a great, the best product though. 450595

Great product. I followed the online video from for a 2017 Chevy Colorado with excellent results. My truck is a 2018 Colorado which has the same wiring (no plug n play like the Silverado). Made sure the color coding of the 4 wires were connected properly as described in the video. All you have to do is pay attention to his instructions. Now I can safely pull my 16 foot trailer loaded with tractor. Thanks, Hugh 554796

Installation was straightforward with help from the online videos. I also installed the ETBC7 universal installation kit. At first I thought etrailer had shorted some parts, but it turns out that the 18140 bracket is sold separately. Had to take back the choice words I uttered under breath. Ended up mounting the provided bracket directly to the hitch with screws which was a little more difficult. As a safety measure--and a little on the overboard side--I also used a dremel to cut a small slit in the center of the provided bracket so I could attach a hose clamp similar to the one in 18140. Space inside the cab for mounting the brake controller was tight. Nonetheless, all works fine per my test meter. Don't yet have a trailer to connect, but meter checks out fine. 443359

I installed this on my 1997 Chevy K1500 pickup to pull my farm trailer, Kubota tractor, and it's implements (total of about 5500#s). I bought my truck new in 1997 with the towing package. eTrailer had a number of links related to the installation, but the most helpful was the one that identified the blue brake and orange power wires that, in my case, were preinstalled at the factory. That made the job significantly easier. What I thought would be the most challenging part of the install turned out to be simple, but only because of pure, dumb luck. Because I had installed aftermarket security and stereo systems shortly after I bought the truck, there was no way to identify/compare the pictures/discussions to identify the hot brake wire under the dash near the brake (other than that it was likely a white or gray wire). The circuit tester (purchased with my order from eTrailer) turned out to be a godsend. Unbelievably, the first white wire I tested turned out to be the hot brake wire! I was very lucky to hit the correct wire on the first try. The first time I hooked up to my trailer, the system worked flawlessly... exactly as the instructions described. And the performance is excellent. Note: I double/triple checked connections as I worked. I highly recommend doing this. Hunting down electrical connection malfunctions is not something you want to do. Overall, I'm VERY happy with my purchase and the support from eTrailer. I highly recommend this product and eTrailer. 98210

Pictures of the install. Approximately a 20 min job. First picture my finger is pointing to the factory plug with the etrailer supplied harness plugged in. Note the harness did not specify that the white common with the ring terminal should be connected to ground. But then again that SHOULD be obvious. I will be towing this weekend so I will rate the product then. One minor gripe is that there is always power to the unit which is a battery drain (as evidenced with the key out of the ignition and the unit stayed on) Not sure as to the impact but the controller can always be unplugged or removed. Sorry for the dirty floor mats in the photos. 115201


Just a quick note, there is an automatic shut-off on the Primus IQ. After 15 minutes or so of in activity, the controller will power down automatically. As soon as the controller detects movement, it comes back on. No battery drain, and you do not have to remember to turn the controller off or on.

Just wanted to follow up with you. I have an old 2004 tundra. I got rid of a 3 year old 3500 Chevy and got in that 04 tundra. I have had a goose neck hitch and pull a 24 ft. With a dove tail, 3 beam trailer with that tundra. I have always had e-brakes, but had a used controller which I had wires spliced into place for the controller. I pulled that trailer for 10 years with that tundra and never really felt comfortable with the e-braking system. I kept that tundra kicked in the ass for 10 years with the loads I pull and was always on caution due to my lack of confidence in the braking system of that setup. We'll, I bought your controller and factory ready quick connect wiring harnesses for my make and truck model. We'll let me tell you that I have never felt so confident pulling a trailer in my life as I do now with the flexibility and control I have on my E-braking system now. I'm still up in arms on deciding wether this is better advertisement for you and the breaking system with the quick connect wiring harness, or better advertisement for the 10 year old tundra that I have always had and continue to kick in the ass with loads that onlookers shake their heads at when they view the work that my 10 year old truck and e-breaking system handles. This new e-breaking system allows me to have the confidence that I can control the velocity of the load I'm hauling with ease. Thank you. 150117

This was bought with a 7/4 plug and a Tekonsha adapter cable for a 2012 Expedition for use with a 26 foot travel trailer. Very happy with this purchase. It was a pretty easy installation, but I did solder & used heat-shrink tubing for the wires in the back if the truck for a permanent connection. Up front was extremely easy. Ford was nice enough to wire all the Expeditions the same, regardless of whether it had a "tow package". The size of this unit is about average, but the bracket is not a large one, so the controller sits closely to the mounting surface. It mounts horizontally or vertically, so I mounted it almost straight up and down, which is good for me. My wife is short, leaving only a few inches from the dash to get knees, and there is no interference or banging into it, even though it's right out into open on the lower right of the driver's side dash panel. There were not a lot of location choices, so that's really it for ease of reach for manual use and adjustment if necessary. It is adaptive, so it does not try to engage too harshly, which makes it super easy to adjust to your truck and your braking style. Brake hard, it engages hard; brake gently and it engages only a little. Press softly, then harder, it reacts likewise. For anyone who'd like a nice controller at a nice price point, this is definitely a great choice. 527500

Have not had a chance to use this yet as we are picking up our trailer over Labor Day Weekend. HOWEVER!! Installation was a SNAP! It took me longer to find the screws I kept dropping than it did to install the cable and control!! SUPER EASY!! Installed it inside the useless hole in the lower dash to the bottom right of the steering wheel on my 1998 F150. Drilled a on inch hole in the back of the compartment and ran the wire through. Secured the metal bracket with the supplied screws and attached the control. I wish everything installed this easy!! Looks great, VERY easy to understand instructions and all the parts are there! 220152


Its now at home in a 2004 F150 and works fantastic! No adapters or relays needed. Plug and play! Controls the brakes perfectly on our 24 camper!

installed on a 2009 F-150 everything was as advertised. It was plug and play. My truck had the wire plug behind the dash so was easy to hook up. I installed it in the hole below the coin holder. To reach the pre-wired plug you have to remove the panel anyway. I don't like any wires showing or anything I might hit with my leg. So did not mount it on the lower dash. You have to pull the plastic box out to unplug the connector. So just cut off the back of the box off and run the connector through the hole and connect to the controller. This way you can remove the controller anytime you want. Also you can see the readout much easier then mounting it on the lower dash. See pics 333618

Product was delivered on time. Installation vehicle was a 2012 Ford Expedition Limited with factory tow package and was a breeze. I purchased the pre-wired pigtail which fit the Ford connector with no problem. I used the snap-in plastic bracket, mounted on the knee panel as close as possible to the center console. I held the bracket in place using painters tape to check the mounting position before driving in the self tapping screws. Start to finish was less than 10 minutes. I pull a 29' tandem axel travel trailer which comes in around 7,000 lbs and so far, stopping has been smooth and even with no jerking. 328184


After a year of use I am very impressed with this controller. Previous controllers I have used tend to be too aggressive on applying the trailer brakes, especially in stop and go driving, but not this unit, it is very smooth. However, when needed, as in one emergency stop last year it pulled us up quickly and straight. I would certainly recommend this product.

Installed this in my 2018 Tacoma TRD Off Road. After removing the sill trim and Kick plate to find the Factory Plug. I took the Bottom left dash down (3 Bolts) and some clips to gain access to the small cubby on the left of the steering wheel. Popped it out, trimmed it to fit with my Dremel and held the Unit in place with 3-M automotive trim tape. I only had to cut the sides of the cubby and a square hole for the plug to the unit. Looks Factory installed. All in all it took a couple of hours to do. my truck has only 135 miles on it so I was extremely careful. As you can see by the pics it's not in the way at all. It could also be put in the center console but it has a wireless charger and I didn't want any Electronic interference or block access to my coffee cup holders. 490872

The controller is super easy to install. I have the plastic bracket mounted low at the bottom dash board of my Nissan Frontier to get the proper angle for operation. When needed I just plug in the end from the wire harness and pop the controller into the bracket with a click. The instructions for operating and adjusting the controller are straight forward. Read them a couple of times or have them with you before you start towing for real. The "boost" feature is a great way to fine tune the controller and you can adjust it "on the fly". A great product all around. 204020


My controller still works great though Ive not used it lately. I still highly recommend this brand and model.

I bought the above brake controller, the ETBC7 brake controller wiring kit, and the Tekonsha plug in wiring adapter for my non trailer equipped 2006 Ford e150 passenger van. I already had the 4 wire plug installed in the van, but not done very well. I started redoing the 4 wire circuit to hide the wiring better, and then mounted the back plug and cleaned up all the wiring in about 45 minutes. I took another 1/2 hour to pull the wire forward to the battery area, and lock it down. It then took about 45 minutes to mount the brake controller inside. Buying the adapter cable saved me a good 1/2 hour or better. The entire thing done in about 2 hours and likely better than a shop could have done. My advice is watch the videos, they had one for a van very close to mine and it made the installation steps very clear to conceptualize. P.S. I'm an Amazon prime member. The brake controller was the exact same price as on Amazon. Amazon however did not have a well equipped wiring kit, nor did they have the harness adapter. I definitely would not have saved money buying on Amazon and I would have lost time due to not having the harness adapter. 198858

The brake controller that I received worked very well. The plug and play brake controller adapter (3016) - not so well. After looking at all the reviews I decided to order the Primis IQ brake controller along with the wiring adapter (3016). I talked to Susan (customer service) and asked how long the wiring adapter was. I wanted to make sure I had enough wire to go from my fuse box to the controller. She told me the length was 35 inches. This was enough for me so I ordered it. Everything came to me in just a few days. Unfortunately I didn't measure the adapter wiring prior to installing the brake controller. When I started to wire the adapter to the controller I found out that the wire is only 27-28 inches long including the plugs. With a lot of stretching I was able to just get the adapter connected to my fuse box and my controller. If you purchase the adapter (3016) make sure you measure the distance from your fuse box to your controller prior to drilling holes in your dashboard or you may have to relocate your controller. I am pleased with instructions that are sent with the product. They are very well done and easy to understand. 568074

The Tekonsha Primus IQ controller is a well made compact unit that is perfect for my FJ. The ETBT7 wiring kit has all you need to go from 4 to 7 pin connectors. I was worried about how to remount the 4 pin, but the new 7 pin has a 4 built in it. It is a very clean install. The kit had everything needed to install, including a test light. The Tekonshcontroller and the wiring kit are high quality and have complete easy instructions, and had everything needed for the install. Etrailer didn't have the ETBT7 in stock when I ordered and I paid for expedited shipping. They followed up with emails and calls to inform me what was happening, and offered to refund the shipping fee. I told them just expedite it when it came in and they did, got to me in two days. I recommend trailer highly, they kept me informed, were prompt, friendly, and concerned, and paid attention to detail. If only other companies followed their example... Excellent prices, Great product line, great company, great staff. I will use them for all my trailer needs. I Recommend them highly. 130304

I had one of these before and it worked well. Etrailer had a great price on it and when I needed to put one on a different vehicle I bought from them. I couldn't be happier. 73894


I sold the vehicle but kept the controller and my new truck has the factory brake set up. I need to get the wiring harness for it as I left it in the vehicle. Ill get around to it one of these days and probably end up selling the controller. Its a good unit and worked like a champ. Which reminds me, I was going to buy some LEDs for the trailer. On the list for this winter I guess.

The part shipped fast as usual and I am happy with E Trailer. I was able to use a plug in adapter so installing this was very easy. I used the included screws to install it under my dash. If you are not using an adapter, this does not come with enough wire to hook it up, you will need more wire. This seems to work fine on my 2 axel landscaping trailer but I have not pulled a real heavy load with it. 2 reasons for the 4 star instead of 5. This is my first brake controller and the instructions left out a pretty critical part in adjusting it. While it says the engine has to be on, you also have to have the brake pedal pressed to adjust it. This took me a while to figure out. The second thing is i have it mounted at about a 30 degree angle (i assume would be common if installed under the dash) and at this angle the bottom of the display is unreadable. There is a dot that indicates boost and power. For example 1.2 vs 12 and .c vs .c. are indistinguishable at that angle. If i lean forward i can see it fine. Minor issues, overall I like it. 526891

I ordered and received my Tekonsha Primus IQ brake controller with wiring harness for my 2012 Ford Expedition. To keep from drilling mounting holes for the contoller, I double backed taped it to the top of the center console. In order to hide the wires, I had to strip some of the braided wire loom protective cover away so to be able to push the wires through the gap between the dash and console. The installation came out very clean and access to the controller couldnt be better. Hooked up the trailer and took it for a drive. Within a few "stops" I had the brake system dialed in.Working perfectly. PICTURES ATTACHED. 493750

Not the simplest thing to install on a mini van (2012 Honda Odyssey Touring) but that's not Tekonsha fault and the etrailer guys have done a great job at explaining what to do. Had I not already had tons of wire and stuff laying around the shop, I would of bought the wiring kit they sell (ETBC7). You can not buy all the stuff that comes with it for cheaper elsewhere! Once all the wiring was installed, hooking the brake controller up was real easy. The instructions are real clear on how to set up the controller too. It's literally just seeing it to a number, driving, and pushing the controllers manual operation slider. It really couldn't be simpler. I chose this controller because it had a low profile mounting option. I knew keeping it out of sight of the wife was my number 1 priority. I was able to mount it right below the steering wheel so I could easily reach it and thanks to it but having to hang on a metal bracket, it's low enough of a profile that are didn't realize it was the until I told her. 444076

Had it for about a year now. Plug and play on my Ram 1500 with the adapter harness sold separately. All wires were long enough and I actually had to tie wrap them up to shorten them. Thats a good problem in my book when it comes to wires on vehicles. Installed it in the length of time it took to screw in 2 screws and plug the harness into the existing plug. I use it mainly to tow a 6000lb dual axle travel trailer. It did take some getting used to the Proportional control as it replaced a cheaper timed one. But once I got used to it I don't even notice its there. Brakes are proportional and stopping distance is about the same as without the trailer and dependent on how hard I hit them. Drove 1800 miles in the Appalachians last month with some incredibly steep inclines. Never failed and performed excellent. It is adjustable and I did have to dial it in, but once done I haven't touched it. Great product, dependable and you get good performance for the price. I'd buy it again. 415554

Products were as advertised. Mount the controller, plug the cable into the controller and the truck connector. Set the boost per the documentation - go towing! How easy is that? 120771


After over a year of using this controller I have nothing but good to say about it. In all weather conditions it allows you to stop your rig under control. This is my third Tekonsha controller so that is the best recommendation I can give. Other two went with the vehicle when sold as the buyers wanted the controller.

This is a good product that etrailer sells at a fair price and ships to the buyer promptly. Plus, it seems they are the only vendor smart enough to automatically bundle the controller and the appropriate connection harness for various vehicles, which makes installation a snap. 229696

This brake is a God send. Not to drop religion, but this is truly a life saver on my truck. I'll be honest, I didn't know my 1994 trailer had brakes so once finding this out and that you can get this fine gem to do all of the heavy stopping thus relieving your tow vehicle of that extra work - I'm getting 1-2 miles more per mile (don't ask me how - I've done the math and I'm still confused how slowing down more efficiently allows for my rig to get better gas mileage) but it does so I'm including in this review! Installed it in less than 5 minutes and tested out how amazing it worked in less then 5 after that. Remember - I didn't know my trailer had brakes, so there's that to be said when it comes to my ability to install something as simple as this brake. Toughest part I had was mounting it. :) Wiring with the pre-wired kit was truly as easy as drinking a glass of water. I will be an etrailer customer for LIFE! 498508

I chose this device based on my trailer repairman's brand recommendation. He usually has them in stock but was out. I got mine before his order came in. He also did not have a wiring harness for my vehicle so I ordered that, too. This is the first time I've ordered anything significant that I knew virtually nothing about. From the descriptions and pictures on the etrailer site it was easy to look up what I needed. I also read on the site about time control vs proportional and then knew the proportional would be good for me. I have a new camping trailer that has electric brakes; need the controller to operate the trailer brakes. The product quality of the brake controller appears very good. The wiring kit is quite substantial. My mechanic will wire up for me this week end and I'll have his opinion then. I am very satisfied with the speed of the delivery and the quality of the products. thank you 84360

Worked great on our two hour trip coming home from the R-Pod dealer. Good paper instructions. The video on U-Tube was helpful when drilling through the fire wall. The Toyota factory harness for the 2011 Highlander gives you no brake wire access, made worse by a knee air bag. After dropping the lower dash panels I was able to insert a flat bladed electrical connector into the back side of the plug going into the brake light switch and zip tie the connection in place. The Universal Installtion Kit ETBC7 is worth evey penny and makes the installation professional. The ETBC7 plugged into the existing four pin trailer plug and completed connections to the vehicle's battery and controller. Two suggestions: 1- The TK90160 should come with longer pig tail leads to reach the brake light switch (I added 4"). 2- The ETBC7 does not come with a plastic wire protector for the fire wall entry point. 469662

Like other reviewers the biggest challenge was getting the cover plate removed (and replaced) to access the factory connection. The connection was at the very top of the wiring bundle and I was able to cut about 1/2" of the tape holding the bundle together very near the connection to gain access without removing or cutting all of the tape. The ground terminal was easily accessed and the installation was quick and mostly painless. The instructions to set the braking level was spot on. I have a Sequoia with a knee airbag and tire pressure monitoring. I place the controller with the open back of the bracket allowing access to reset the tire pressure monitoring switch. 103222

Used the Primus for a 2006 Cayenne Porsche. Had it installed by a Porsche dealer in Denver. There were some issues about a relay that needed to be installed. The relay issue was resolved by a second Porsche dealership in south Denver that discovered why my magnetic trailer brakes were pulsing and destroyed. Now Primus and etrailer know about this relay in the installation of the TK901160. Make sure you ask and install this relay or you will have issues with the trailer brake controller and your trailer brakes. The Denver Porsche dealership made good on it's mistake and the south Denver Porsche dealer corrected at no charge. Works very well now and I am happy with both Porsche dealerships. I believe a bulletin was sent out by Primus to all Porsche dealerships about this issue. Very good product from Primus and recommended by the Colorado Porsche dealerships. 370169

Just bought the Tekonsha Primus IQ and installed it. Haven't used it yet, as I pick up my first travel trailer next week. Product is solid, packaged with ample, clear instructions, wiring and mounting hardware. Lower dash on my Honda Ridgeline slopes steeply so I fashioned an L-bracket from 14 ga. steel bar and secured to side of center stack (see photo). Nice and level. Wiring to my harness was a bear, just because of where my connector was buried; needed the YouTube videos. Price was much lower from etrailer than any RV dealer around here. Arrived in less than a week. Think I made a smart choice. If it works as advertised it will get a fifth star. 376393


The brake controller works great. Initially after installation the unit was not getting any power. After checking my connections I discovered, in the trucks fuse panel, that there had never been a fuse installed for Trailer Brakes even though the wiring harness provided a connection point. Easy fix.

I got the brake controller and installation went pretty good on my 2008 GMC Sierra except for one thing. I watched the etrailer video on-line It mentions there are two wires under the hood that get connected to the posts on the fuse box. I could only find one (one between fuse box and engine), I couldn't find the one near the fender/sidewall. I called etrailer for help and the person did have any advice. I went online and found the answer in an auto forum - the other wire was under the fuse box. You have to remove the 3 bolts on the fuse box and pull it to get the wire which is wrapped around a wire bundle under there. Please add this information into your knowledge database so you can tell future callers where to find the wire. Also the 2 nuts needed for those wires on the fuse box: one is 6mm and other is 8mm (1.25 thread). 456374
