Proportional brake controller automatically levels when mounted within a 70-degree vertical range. Includes digital display, 3 boost levels, battery protection and continuous diagnostics. Easily transfer between different automobiles.
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.
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 Acura TL. 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 Weight||Boost Level||Increase in Initial Power Output|
|Less than tow vehicle GVW||B1||13%|
|Equal to tow vehicle GVW||B1 or B2||13% or 25%|
|Up to 25% more than tow vehicle GVW||B2 or B3*||25%|
|Up to 40% more than tow vehicle GVW||B3*||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.
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 Acura TL'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:
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 70 degrees, and the controller will level itself automatically.
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 Acura TL. 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.
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 Acura TL, and the other end plugs into the controller - no hardwiring required.
Note: If a custom brake-control wiring adapter is not available for your Acura TL, 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

Video of Tekonsha Primus IQ Trailer Brake Controller - 1 to 3 Axles - Proportional
Videos are provided As a guide only. Refer To manufacturer
installation instructions And specs For complete information.
Today, we'll be reviewing Part Number TK90160. This is the Tekonsha Primus IQ Trailer Brake Controller for 1 to 3 axle trailers. This is a proportional braking system. The brake controller is going to activate the trailer brakes in proportion to your vehicle's braking action. It's going to automatically adjust the trailer's braking based on deceleration of the tow vehicle. It activates immediately, so theres no pausing like when using time-delayed brake systems. It also has automatic leveling ability.
It has an internal sensor that's going to detect deceleration even if your controller is not mounted flat. Now, you can position this anywhere from 0 degrees, which is level, to 70 degrees in the vertical plane. It's going to provide you with 3 Boost levels that's going to let you adjust initial braking power and aggressiveness. One of the great features about this is that it offers continuous diagnostic checks, so that way, it can alert you of any potential problems. It has an integrated safeguard system to protect your trailer and vehicle. It's also going to minimize drain on the car battery when not in use, as well as prevents the trailer brakes from overheating by reducing the power output to them during prolonged stops. This part of the brake controller right here is a easy-to-read LED display which I'll show you in a few moments.
It also has a built-in slide bar manual override. Here on the back, its going to feature a quick-disconnect feature that lets you easily remove and store the controller when not in use. Its going to come with wires, so if you have a system where you need a hard wire, you can see how easily that connects on there, but we do offer plug-in, vehicle-specific brake controller adapters. Those are sold separately. You can find those on our website.
Those can be used for certain applications to reduce installation time. Now, if a custom brake control wiring adapter is not available for your vehicle, you will need to either take into consideration a 20-amp circuit breaker or a 30-amp circuit breaker, depending on your brake application on your trailer. We do offer those on our website. The 20-amp circuit breaker is Part Number 9506P and the 30-amp circuit breaker is Part Number 38630. You can also see etrailer.com's exclusive 7 and 4-Way Brake Control Installation Kit, Part Number ETBC7. That is sold separately if you dont already have a 7-way plug at the back of your vehicle. This is designed for trailers with up to 3 axles, which is 6 brake assemblies.
It's designed for use with electric brakes only, so keep that in mind. Go over the dimensions real quick. Overall width is going to give us a measurement of about 3.5 inches, and this is without any of our brackets installed. Overall length is going to measure right at 5 inches, and then the overall height is going to measure about 1.25 inches. It does come with a mounting bracket, this one right here, simply just slides over the controller. It snaps into position. This one goes underneath your dash. You can mount that. It has numerous mounting options. As you can see there as well, it has a tilt feature. All the hardware that you need to get this on mounted up is provided. We're going to take our external power here and were going to hook up our brake control system. That way, you can see the brightness and the functions of the LED. Once we have our connections made, you'll see the LED display come on. There we go. We have our manual bar override here. We can also adjust that level, simply using the thumb dial there. We also have the boost setting button. It offers our different settings. Its a really nice little system. That's going to do it for today's review of Part Number TK90160. This is the Tekonsha Primus IQ Trailer Brake Controller. .

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
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
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

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 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
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 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 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 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 purchased the Tekonsha Primus IQ Trailer Brake Controller and the wiring kit for my Toyota 4Runner. It was simple installation and the customer service was EXCELLENT! They sent me extra schematics I needed by email and was very supportive! I will definately do business with them in the future. 78575

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

Super easy installation. Clear, thorough instructions. Everything you need to install included. Digital display codes are a little quirky so you'll need to keep the quick start manual handy until you get used to them. 94094
by: Sam S.10/09/2013
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

Controller and wirering harness arrived in one night. Installed easy and clean in an hour and worked properly ever since. True plug and play with my 2013 E-350 xlt van. The OEM tow package connector is on the back of the coin cup in the dash. Great thing is that the Primus IQ fits perfect in the holder after you open up the back of the coin holder a bit for the connector. 183256

I received this brake controller and the cable designed for connection to my 1995 F150 truck within the time I was told. I hooked them up and I was ready to tow my trailer. It seems to work well, but I will not know until I take the RV trailer out for a run, soon. Thanks for the great service. Also, This was the second brake controller I tried. The first was a Curt brake controller and failed to work properly, so Katie of etrailer helped me pick out another brake controller (this Tekonsha Primus model). Installing the wiring and 7-pin connector was another story. Careful placing your order, if you make an error you will be responsible for return shipping. better to call in your order and verify that the parts you are ordering are correct for your vehicle. 164341
Outstanding, from start to finish. This was a super simple and easy installation process. I started by watching the e trailer video to see what the installation would be like in my vehicle. They give detailed instruction which allowed me to inspect my vehicle before purchase to see if this will fit "as advertised". I bought the brake controller and special pigtail for my truck and all I needed was to drill 2 holes in the bumper for the receptacle (trailer plug), plug in the trailer connector, install bracket under dash and plug in the pigtail and the project was complete. Very easy. Instructions for the setup to trailer are simple and clear and very easy to complete. I am completely satisfied and highly recommend this product and e trailer to everyone. 228080

Purchased the Tekonsa Primus IQ controller with wiring adapter for my Dodge Ram. Shipment arrived quickly and was exactly what I needed. Installation was a piece of cake. Cut an opening in the plastic stock dash location. Plugged the adapter into the Dodge plug under the dash and into the Primus. Worked perfectly. No fuss. Installed in about 10 minutes which included the time to cut the opening.. Picture will be poster... I was so happy with the service from etrailers that I ordered the Blue Ox Swaypro hitch. Thanks ETrailer.com! 112238

by: Ray B of Colo.11/18/2013
I purchased a Primus IQ from our local NAPA dealer and had already installed it in one of our Dodge trucks before I learned about Etrailer. Needless to say it cost a bit more than the one I ordered from Etrailer a couple weeks later. you cant return electrical products once installed. I received the one from Etrailer in a very timely manner. I was hoping it wasn't a #2 for it being so much cheaper, but it is just fine and installation was no problem because I already had Tenkonsha Voygers so just chop the wire and install new control unit. We have two trucks and pull various trailers, so am real happy with product and will further order trailer items from ETRAILER.COM. Thank you, just Ray 107693
This is very easy to install and adjust and the service at e-trailer is great Christy was a great help and shipping was fast 138221

I bought this product after reading several reviews. I recently purchased a Fun Finder 189FBS Travel trailer, and I needed a Brake Controller that was proportionally controlled. After my first trip with my 2012 Rubicon/ Fun Finder; I am very pleased with my purchase. This controller works best for my setup, on the "b1" boost level. Setup and installation took less than 2 hours, and I did it myself. The instructions and reference video from etrailer.com were very helpful. I was quoted nearly $400 to install this controller from my local RV shop. I bought it hear, spent 2 hours, and saved $250. If you can crimp a wire, and run a drill- You can do this! 80929

The Tekonsha Primus along with the Tekonsha 3035-P Ford adapter are awesome producs, tested it right after installation outstanding results. Installed on a '07 F150 XLT w/ tow pkg., adapter plugs in behind the OBD2 port, PLUG 'N PLAY (with adapter). 175218
by: Brent B04/07/2014
This product plugged right in and worked perfectly as it should. I like the different boost levels as a quick adjustment between loaded and unloaded trailers. No messing with the gain controller to keep the tires from sliding. The special dodge plug made install a breeze and less than 5 minutes. Much better than splicing into wires. Plus eliminates the need to hunt for the correct wires. This controller works off of inertia so as it senses your truck braking it applies equal braking to the trailer eliminating the jerk experienced from other controllers. Shipping from etrailer was quick as well. Great overall product at a reasonable price. 124031

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
A lot better than the voyager. More helpful and easier to test the system - truck and trailer 124354

The electric brake works great. It was easy to install and set up. 142469
I bought this brake controller over a year ago. I installed it in an 03 gmc envoy and was pulling a small hybrid rv that weighted approx 2750 lbs, (single axle). The controller was easy to install and adjust to my vehicle and trailer. Works great. I noticed that it automatically adjusts the amount of voltage output to the trailer brakes if you are on an incline or decline. I now have it in an 05 GMC Yukon pulling a larger rv about 3600 lbs (double axle). The staff at etrailer were very helpful and kind. They had good info for the DIY. I definitely recommend this product and etrailer.com 245963
by: Kevin G.09/11/2012
Product works great, as advertised. The Tech at the RV dealer commented on the reliability of this brake controller, and the install literally took 15 minutes, start to finish. The supplied factory wiring harness made quick, simple work of the installation. The video on the etrailer website is right on the money as well. I have dealt with etrailer for all my towing needs since 1995, and they have never let me down. Great, quality products......quick delivery, and customer service that is second to none. There is no reason to shop anywhere else. Thanks etrailer.......you are the best! 54172
I ordered mine with the wiring harness for toyo and Lexus. Everything plugged in nicely and fit perfectly in a Toyota Sequoia under the steering column on the right side. The only suggestions is the that the factory wiring harness in the sequoia has absolutely no slack, so it you order this with an adapter for this make and model, it is a little to short to run it to where I have it. I really had to work to get it mounted. If it had a longer run by about 6 inches it would have been a piece of cake. I still gave it an excellent rating because other than that it was a 5 minute install. 116521

I purchased this trailer brake controller as we had recently bought a camper and the SUV we are pulling it with does not have one. I am going to use it this weekend for the first time. When I called to order it I had no idea about these. The salesperson, Cathy, was extremely helpful and was "over the top" in helping choose the correct one as well a finding installation videos as well as getting the correct accessories for my vehicle. It was a really great buying experience. The installation was very easy and it lit right up after connecting it. Can't wait to try it! 209981
by: L. Miller06/17/2015
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

While I have not had the chance to use it yet pulling my trailer I picked this particular unit because of the reviews it has received from people that have and are using it. I had it professionally installed and it is working as the instructions say it should. The company that installed it had nothing but good things to say about it as well. I especially want to thank Nicole for her help and customer service she provided to me and I can promise you that all my future trailer needs will be purchased from your company via Nicole. Big Thanks to all of you. 56414

Fast and got what I ordered...:) 156275
Great controler for the price. Easily mounted and set up using the vehicle specific harness. Installed in a 2003 Toyota Sequoia just under the key in the flat of the center cover. Perfect for the 0 - 70 deg mounting location required by this controler. Setup and operation just as was stated in user manuals. eTrailer was great as well, everything came together and on time. 84801
I am unable to correctly rate this product at this time because there is no Dodge 2013 harness with which I can attach it. If/when the harness becomes available (a year plus after the truck came out, of course), I will re-review the product. Note that lack of this harness is NOT the fault of eTrailer, but if you're purchasing this for a 2013 Dodge truck, you might want to wait. 73972

Plug and play is a true definition. My family was bugging me to go boating this last weekend and being the procrastinator that I am I had not yet installed a brake contoller on my 2011 Ram yet. Got the controller and Harness in the mail on Saturday after only 3 days since order was placed. The install took 10 minutes max including the bracket install and away we went to the River. Thanks etrailer!!!!! Would have never heard the end of it from my 14 year old daughter if we would not have made it boating!!!!! 46597

I have had a few different trucks in the past, all with brake controllers, some factory some not. So when picking one for my truck, I wanted something with as few a knobs, dials, etc as possible. I looked around on the internet and found the Primus, it was the middle of the road as far as sophistication and basic. It was shipped promptly and arrived within a few days. The installation was easy with great instructions. Would recommend to anyone who wants ease of operation without spending a fortune to get it. 91572

I am replacing a 15 yr old break controller that was flaky. The new technology is quite an improvement. Not having to compensate for the angle of the controller is a real plus. This unit appears to be high quality with a robust connector. The trouble shooting display should be a real help in time of need. The documentation is excellent. I did have one display question that was quickly answered by etrailer. I have a light weight trailer and I expect this controller will perform well. If not, 'I'll be back!' 229056

The tekonsha controller was easy to install with the help of the instructions, (very well written), and the video, specific to my 2006 Dodge Ram. Set up was also quick as I dialed the power setting to 7, and have just the right amount of braking for my empty trailer. When I loaded trailer for the first time, I adjusted the boost level to the b1 position and that was all that I need to do to have the safety of well adjusted trailer brakes at finger tip control. Very pleased with this pur hase. 109795
I have never used trailer brakes nor a controller. However, I can say that it works as advertised and reviewed. We hooked the 19 foot trailer to the newly wired (by me) Xterra, which it outweighs, and headed out. I was using a setting one choice too low. But as soon as I popped it up to b1, it stopped like it did without anything hooked to the tow ball. There are lots more bells and whistles on some of the other models, but this is all I need and look forward to lots of hauling and camping. 215900

I was very pleased with the installation. I had a dealer tell me it would take about three hours, which I knew was a stretch, to install a brake controller on my 2009 Dodge Ram. Including opening the package and looking at the installation procedures, it took me fifteen minutes to install. I had looked at the on line information that was provided befor purchasing the brake controller. It was a great experience. I have not had a chance to see how it works, but I am sure it will be fine. 141743

I purchased the Tekonsha Primus for my 1990 GMC van. We purchased a camper trailer and needed a brake controller installed. I also ordered a trailer wiring harness and connector kit. The order from eTrailer came on time and very well packaged. I was surprised as everything needed to install the controller and plug wires was included! The install took a while due to the age of the van but the instructions were great. It is working fine and ready to go on its maiden voyage! 242722

This item was in stock and shipped the same day. It arrived undamaged and the installation took about 15 minutes thanks to the wiring adapter that let me directly connect this unit to my 2007 Mercury Mountaineer. Hard to image that it could be easier than this. 91296

I installed the Primus IQ Brake Controller in my 2010 Tacoma using the Tacoma cable harness supplied by etrailer. I mounted the controller directly under the steering column as I had read issues about the LED's being a distraction for night driving. In that position, I don't see the lights other than a glow under the steering column and the manual override control is within quick reach. This install took 20 minutes and all systems powered up as specified. 185605

This is my third Tekonsha brake controller and the quality is excellent. I've got to say that your installation video saved me a lot of grief. I spent about 20 minutes trying to find the factory connector under the dash without success. The video showed me exactly where it was hidden. Without your help, I'd still be looking!! Your salespeople were helpful, too. Anything else I need for my trailer I'll be using you- and recommending you too. 108744

Excellent service, one stop shopping on web, you guys had everything that I needed in one place. After the order was place I was notified that shipping would be expedited at no charge, I placed order on Thursday and received all products on Tuesday. I also received several follow up emails from the company to make sure everything arrived and I had no further questions or problems. I Could not ask for a better experience or a better company. 148040

I cannot rate the Primus IQ controller yet as I have just received it.However, the instructions/disk are very clear and straight forward. What I can comment on is eTrailer.com. I don't think I have ever seen an online retailer with better customer service and online support (videos showing step by step installation instructions for almost every specific model truck) It took a real effort on eTrailer's part to provide this. Great job! 35943
