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 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

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.

Video Transcript for Trailer Brake Controller Installation - 2016 Ford F-150

Today on our 2016 Ford F-150, we're going to take a look at and show you how to install the Tekonsha Primus IQ Trailer Brake Controller. This proportional brake controller works for one up to three axles. Part number on it is TK90160. We're also going to be using the Tekonsha Brake Controller Adapter. This part number is 22292. Here's our brake controller once we have it installed. The Primus IQ is a proportional brake controller.

This is going to operate in proportion to how much braking we're doing in our truck. The accelerometer that's located inside senses when we hit the brakes, whether it's in a normal operation or in a panic situation, and applies the brakes accordingly to our trailer. The benefit of to that is that we don't have to wait on our time delayed systems. Those are going to start at the bottom and then slowly ramp up. This one can instantly send the appropriate amount of braking power to the rear of the vehicle for us. Another great thing about the Primus IQ is going to be the safe guards that we've got built in.

It draws very low power when not in use from our vehicle's batteries, so we don't have to worry about battery run down. It's also going to safe-guard the brakes on our trailer. For prolonged stops at stop lights or stop signs, it's slowly going to decrease the amount of power being sent to the brakes on the trailer so they don't overheat. Under normal operation as we head down the road we'll see the C indicated on our brake controller. If for some reason we we're to have a connection failure, it will then start immediately flashing NC, NC. That's going to indicate to us that we've got no connection.

Once we're re-connected the C is going to come right back on indicating to us that we've got a good connection. Here's our manual over ride lever. As you can see that's going to allow us to go right up to whatever our maximum setting is. Whatever we've set the brake controller as far as the gain goes, as we hit that it's going to take it right up to that maximum that we've got set. Even in the case of an emergency when we're reaching down here, maybe in a little bit quicker situation or maybe more in a panic situation, we're not going to overload the brakes on the trailer and risk locking them up. Here you can see we've got a boost mode, B1, 2, and 3. It's indicated by an LED that's going to sit down there in the corner.

Right now it's off so there's no LED. If we switch it into boost 1, eventually the B1's going to go away but that LED's going to be on there. That's going to indicate to us that we are in a boost mode. That allows us to fine tune our brake controller. That's going to set how quickly and how aggressively those brakes are applied. That's used mainly when our trailer begins to become very heavy in relation to the vehicle. We need to boost that up a little bit just to help to control our braking. Now the gain that we're going to set, this is going to depend on driving styles, on trailer load, on road conditions. Every time, even with the same size trailer, we may have to adjust this a little bit. Really easy to do as you can see with that thumb knob right there. We just rotate that forward or back and adjust it. As far as mounting the IQ goes, we've got everywhere from zero degrees, which would be perfectly level, all the way up to about seventy degrees as long as we're keeping it inline with our direction of travel. We want it to be straight this way. That allows the accelerometer inside to be at it's most effective. The first thing we need to do is get our shroud out of the way that's going to be underneath this side panel which we're going to remove. Now this is going to have a bolt located right up here on the side. We're going to have one on each side. That's what it's going to look like. Take the one out here on the drivers' side. We'll do the same thing on our passengers' side. Now on our passengers' side we want to reach up right at the very tip of this shroud, just about there, and if we pull out on it you see there's a little clip that we separate. That'll allow this side to come free. Should have another clip there, and then we'll get the last one right over on that corner and pull it out. All right now we'll set that aside. We'll put it back in once we get our brake controller in. Now we come right down here to the bottom and we want to just carefully work this out and separate our clips. Now we've got our little cubby hole that's right behind that rectangular shaped hole. It should be plugged right into the back of that. You see it right there What we're going to do is just allow that to come down an we'll pull it right over here. You can see we can pull it out right here to where it'll be easy to connect to. Now we'll get our dashboard reassembled here. Cubby hole's going to go back in. The key with getting this put back together is just making sure that our clips line up. Now let's put our shroud back in place. Now we're ready to grab our pigtail, line it up and slide it in. You want to hear that audible click and then you'll be able to push and pull on it without it coming apart. That way we know we'll have a good connection. Next we need to just set that aside for now. Let's get our bracket mounted. We want the bean shaped hole to be rear-ward. Then we can use our provided screws and go right up into the bottom of our dash. Of course we checked behind there before to make sure we don't have any wires or anything that run through there. You can see, nice and secure. Now we'll take our pigtail. As you can see slides right into the back of the primus there. To mount it we'll just bring it up into our bracket and line up our holes. I always like to mount them as high as possible. I don't necessarily care too much about pivoting on this one. We'll use our provided screws that are going to come with it. Those will go right through our bracket into the holes already in the side of the brake controller. As you can see, nice and sturdy. Now once we've confirmed that it's working for us, we've tested it out, all we have to do is take our excess pigtail, zip tie it just kind of tie it up out of the way there so we don't have to worry about it coming down and getting hung up on our foot. Now with everything working properly that's going to complete today's installation of the Tekonsha Primus IQ Trailer Brake Controller. This proportional brake controller works for one up to three axles. Part number on it is TK90160. On our 2016 Ford F-150.

Replaced an older brake controller with the TK90160. Installation was very straight forward and took less than a half hour. Hooked up the trailer, went to an empty parking lot, tested everything and adjusted the Boost feature. This unit is a superior brake controller. I do a lot of freeway driving as well as mountain roads (ie steep stuff) and I love the feeling of the trailer and the truck’s brakes working together. 563689

install would have taken minutes on our Flex if Ford had left a few inches more wire on the connector. After getting supplied connector (Ford sent both halves of connecter in case of hard wiring) off, install was easy and everything worked as I hoped. 556799

The brake controller and corresponding cable were exactly as advertised. Everything was delivered promptly and all items arrived in excellent condition. The videos of the installation provided on the website were very good and made the decision of the purchased easy. I am using this to help with electric brakes on a 38 foot travel trailer. The ease of installation was fantastic.The site has a wide variety of products and I am extremely pleased with my purchase. I will continue to do business with your company in the future and I will recommend it to anyone who has a trailer or travel trailer. Awesome experience all around 543923

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

I have not hauled with this brake controller yet, but given the ease of installation and simplicity of controls i'm not sure how i could be disappointed. For my hauling needs (Only a 6k gvwr 2 axle trailer) this is perfect and a reasonable price for a proportional controller. Better yet was etrailer.com not setting false expectations on arrival. There are "two-day guaranteed" shippers that often fail to meet, while etrailer estimated a realistic travel time and actually beat it by a lot! 554652

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


Comments
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.

Can you tell us exactly what the issue was? According to the Tech Services folks at Tekonsha, theres nothing unique to your model year Escape that would prevent the successful installation of this brake controller.

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

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 etrailer.com 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

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

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.

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

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

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 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 etrailer.com, 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

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.

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

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

Great product. I followed the online video from ETRAILER.com 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

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
