Proportional Braking

The Primus IQ electric brake controller supplies power to your tow vehicle's brakes proportionally. This means that your trailer will brake at the same time and with the same strength as your vehicle - even when in reverse gear. So, if you have to slam on your truck's brakes, the trailer's brakes will respond instantly with no delay. Thus your vehicle's brakes won't be overworked from trying to stop the entire load, resulting in less wear and tear.


Power Boost for Heavy-Duty Towing

Aside from smoother, more efficient braking, the Primus IQ also offers a boost feature that gives you more initial braking power for those times when you're towing heavier loads. The boost setting sends either 13 or 25 percent more power (depending on which setting you choose) back to the trailer brakes, thus compensating for heavier loads. You can also boost the power manually with the push of a button. This will send more power to the trailer brakes exactly when you need it most, and your fully loaded rig will brake smoothly and comfortably.


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 hills or through the mountains. Simply mount it in your cab at an angle that is between 0 degrees (level) and 70 degrees, and it will level itself automatically.


Installation is a snap. After mounting the unit using the included pocket mount, 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 slide it out of the pocket mount.


For even easier installation, a vehicle-specific wiring adapter (sold separately) is available for certain vehicles. One end of the custom adapter plugs into your vehicle, and the other end plugs into your controller - no hardwiring required.


Note: For vehicles without brake-control wiring adapters, one of the following is 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) that includes all the parts necessary to install the Primus IQ brake controller.

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.



by:

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

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.

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.



by:

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

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.

I've been running the Tekonsha Primus IQ for just over a year now. Very pleased w/ it.
Simple set up & operation. I tow a variety of trailers w/ my '07 2500 HD including dump trailer w/ firewood, car hauler, and enclosed cargo trailer. The weights are anywhere from empty, to 5k. Very easy to adjust as conditions change. I borrowed a trailer from a family member and the controller picked up a short. Come to find out a wire was pinched from ramps being slid in on the underside. The digital screen notified me before loading it up and hitting the road. I would recommend this product.



by:

Works like a dream on my single axle 3200 lb travel trailer and my 2017 Toyota Tacoma. Like many of the other Tacoma owner reviewers, I mounted my Tekonsha Primus IQ controller in the small cubby to the left of the steering wheel and ran a couple screws up through the lower switch access to mount the bracket hidden inside the dash. Ended up looking like a factory install, exposing just enough of the unit to access the controls and read the display.

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.

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.

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. ;=)




by:

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

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!

2011 f150 3.5EB XLT superCrew. Easy plug and play install with the harness I bought also on etrailer, the problem was mounting. I hated the way the supplied mounts looked and didn’t want to bump into it. With some careful measuring and a hacksaw I was able to mount it inside the “plastic cup thingy” that fills the void where the factory controller would be. Attached pictures, the factory plastic cup thingy screws keep it locked in place and the supplies screws let’s you mount the controller into the plastic cup. Looks crooked with the white/silver plastic covering but it is aligned with direction of travel and level, also berey snug and mounted solidly.

Took me about 10 minutes to install on my 2000 Chevy Silverado. Plug and play.

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.



by:

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



by:

Prompt shipping. Very helpful in answering questions about the installation when replacing the controller.



by:

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.



by:

Works on my 2012 Honda Pilot. The plastic mount makes it so you can remove it for security purposes.



by:

Loved this thing on my 4Runner towing our 4,000 pound trailer over 8k miles last summer. Saved us at least twice on the Highway and nice to adjust the sensitivity for city.



by:

I installed the Tekonsha Primus IQ Brake controller in my brother's 4 Runner just before he and his wife took their small (18 ft) camper on a month long trip out west. It did what was expected of it... Proportional brake control, with little adjustment after initial set up!



by:

I haven't hooked up my trailer yet but the connecting and mounting instructions are easy to follow and my vehicle came with a brake controller wiring pigtail which made installation even easier. It powers up and responds the way it is supposed to. I have no doubt it will work properly based on hundreds of other 5 star ratings.



by:

Only used on last year's trip,worked flawlessly once set.Would recommend.2005 f150 with factory tow package.



by:

I love these controlers. Can adjust perfectly and no jerking of the e brakes. Big on stopping whether it’s a hard or soft stop. No locking up of the trailer wheels.
