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

See also etrailer.com'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

This adapter plugs into the 4-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.

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.

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

2012 Honda Pilot

Perfect interface between the controller and the factory wiring. I'd have given it 5 stars if it were a wee bit longer - say 8 more inches. On my 2012 Pilot, I mounted the controller in the bin right below the radio because it just seemed in the way of my legs in the more normal position above the accelerator on the dash. The cable wasn't quite long enough for that and I ended up fabbing my own and put this one in the box for the next time. 434856

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


Still working well. Keeps RV battery charged and 12 volt refrigerator cold when towing on the highway.

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

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

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 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

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

Product could not be installed in my Ford Escape as recommended. Had to trade it at the installers for a different model. Disappointed. 572598


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 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.

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

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

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 what the doctor ordered for the customers Honda Ridgeline. Unbilivably, though the truck was completely wired from under the dash from the factory since it was purchased new with the trailer package, the dealership was oblivious to the fact that a brake controller was needed and were dumbfounded on where to get one, or where the connector was located in order to install it. Found the controler on etrailer.com and the connector location on utube. 228914

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

Thanks to your very detailed videos and the fact that my truck has the factory tow package the installation was a simple process.

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

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

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.

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. 375303

Installed quickly an easily into my 2009 GMC Sierra 2500HD by wiring up to the factory harness. Be sure to watch the etrailer.com 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

2017 Honda Ridgeline

Hello, as requested I have attached some pics of the brake controller after installation on my 2017 Honda Ridgeline. I have a lease vehicle so I did not want to drill any holes in the vehicle to mount or run wires. So what I did was install the mount bracket upside down and place a strong commercial velcro patch to the brake controller mount and to the tray area that it is sitting on. Then I slipped the wire harness between the crack in the IP and the lower console and tucked it up behind the dash so it could not be seen. The velcro holds the brake controller quite secure. This way I can remove the controller and reuse in my next vehicle without leaving any permanent marks or holes to this one. Anyway , just thought I would share… As far as the controller. I am very happy with its operation and functions. 523633

2017 Honda Ridgeline

I gave this a 4 star just because I haven't been able to hook up the trailer yet. The Primus IQ brake controller light is on so I'm assuming it will be fine. The harness arrived in good time. I was able to hook it up in my 2017 Honda Ridgeline in about 20 minutes. The longest part was finding the connection! It was above and left of the parking brake. A headlamp really helped. It's very tight in there so I could use only one hand and did a lot of it by feel. In the picture you need to follow the red wire to the connection. The brake controller I mounted on the plastic in front of my right knee. 321040


Update - Everything worked fine. We went on several trips with our trailer and no problems at all.

2016 Honda Pilot

Just bought a Prodigy 3 and on my first trip with our light weight [email protected] clamshell with electric brakes pulled with a 2016 Honda Pilot...very satisfied. I installed a factory hitch and harness and the cable etrailor provided snapped right in. The trailer is under 2,000 lbs so I opted to bet the boost to zero. So far so good. The only issue is it seems to apply the brakes more firmly when going over rough pavement, otherwise the braking action is very smooth. I didn't want to mount the controller bracket permanently so I bent an angle plate into a U shape and pop riveted it so it would hang in the lower trim panel. 407957

Honda Ridgeline

We have a Honda Ridgeline and this part plugged into the factory plug that was under the dash by the emergency brake petal switch. It was difficult to get to, but success was achieved. This was needed for our camper trailer. This made it easy, no hard wiring, just ordered the part for the Ridgeline and then plug and go. The brake controller plugged into the other end and now I am a happy camper. It worked, I blew a fuse while installing, must have touched something? No problem though, replaced it and was all was good. 202033


After one year, it is nice to not even think about it. I love products that work correctly. Gives one peace of mind. This is a great product. . thanks etrailer and Tekonsha for being wonderful companies. . . jim

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

Arrived on time and supper easy installation with the wire kit, plug and play. Can’t wait to take out the trailer. Need some more miles on my new Nissan Desert runner. 565486

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.

Replaced my almost 20 year old Tekonsha controller with this new one and it works great. Installation was easy. The only reason I didn't give it a 5 star review is because of the plastic mounting bracket. It does not hold well. I will be installing the metal mounting bracket. 432173


This brake controller works beautifully with all of the trailers I pull. I pull about 4 different trailers and can adjust it easily for all of them.

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

Installed in my 2014 GMC Acadia in about 30 minutes. Used the GMC plug-in wiring adapter. No problems. Looks like it was made for that location. 556263

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

I installed TK90160 on my 2007 Sierra 2500 Diesel because I got tired of paying GM to repair the factory brake controller. It works great. Easy to read and simple to install. I used the installation diagram supplied by etrailer to complete the job. I tow a fifth wheel RV. 573301

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

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.

Order was received quickly and installation was easy. Silverado has a tow package, but was in need of a brake controller. The Primus IQ should work fine for my needs. The pin in the RV plug for the electric brake connection does not have power to it on my truck. Once I get it figured out, it should work great. Thanks again for the quick response in receiving it. 554897

Cheapest Tekonsha progressive controller (progressive is quite important with heavy loads, transient road conditions, short tow vehicle wheelbase, etc). Bought it with the OEM integration harness (thanks etrailer, this made things SUPER easy) mounted the "clip" bracket at the bottom of my console below the 4WD selectors with double side tape and the screws provided for good measure. Haven't tested yet but went through all the diagnostics and worked great! 548728

The product is exactly as described. Installation was easy using the vehicle specific cable. Received the controller yesterday, installed today, have yet to connect trailer and try. 573535
