Gain Power Adjustment
You can adjust the gain (also known as output) with the thumbwheel on the front of the controller. Gain lets you set the maximum amount of power that will be applied to your trailer's brakes. A heavier trailer will need more power to achieve smooth, safe braking, while a lighter trailer will need less. Typically, the gain is only readjusted when you experience changing road conditions or if the weight of your trailer changes.
Power Boost for Heavy-Duty Towing
The boost setting controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. You can adjust this when you're towing heavy loads and you need more umph to bring your trailer to a stop. Your tow vehicle doesn't need that much power to brake in time, but your heavy trailer does.
Depending on the level of boost, your trailer brakes can start at either 13 percent or 25 percent of the set gain. What this means is that, instead of starting at 0, the brakes will start at 25 percent and get to 100 percent sooner. This keeps the trailer from pushing your tow vehicle forward.
If your trailer weighs less than your tow vehicle, no boost is needed. But, if you want your trailer to lead the braking, you can select level B1.
Boost Levels:
| 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.
To adjust the boost, use the blue push-button on the top of the Primus IQ.
Slide-Bar Manual Override
The Tekonsha Primus IQ comes with an easy-to-reach, slide-bar manual override, great for stopping sway or controlling your trailer's momentum in emergencies. To engage the manual override, just push the slide-bar to the left, towards the center of the controller. This will activate the trailer's brakes and brake lights without you having to apply the brakes on your tow vehicle, perfect for limiting trailer movement while you're cruising.
Quick, Simple Installation
The Primus IQ can mount between -90 degrees and 90 degrees vertically, but the brake controller still needs to be horizontally level and parallel with the direction of travel.
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 remove the IQ for storage when you're not using it, just unplug the unit and slide it out of the bracket. With a replacement wiring harness (sold separately) and replacement bracket (6927 - sold separately), you can even transfer the IQ to another vehicle.
Installation Accessories
See 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
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
Proportional Braking
The Tekonsha Primus IQ brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.
The Primus IQ uses an internal inertia sensor to detect how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.

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.

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.

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

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.

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.

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.

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.

what year Tundra in pics . I have a 08 and I am going to get an IQ for it . do you still like yours ? i guess a ground is needed ? I see what looks like a one white wire with harness
by: alan01/18/2017
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

by: Shawn W.04/10/2020
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.

Still working great
by: William03/02/2021
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.

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.

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.
by: David06/17/2014
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. ;=)

The controller works good and am quite happy with it.

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!

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.

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.

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: Christian03/30/2018
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: Adam12/10/2023
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.

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.

I finally installed the brake controller and it was easy to follow the instructions and it worked perfectly during my test runs. Shortly thereafter the wife decided the Expedition was too large for her to drive comfortably and we sold it. Not my first experience with Tekonsha brake controllers. It is a reliable product.
by: Garry04/07/2018
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.

Installed easily and now trailer brakes better with truck with no lock ups and is easily adjustable to road conditions while in motion. It is very nice to look at display and see the trailer plug is or is not connected.

What I have really appreciated is the ability to adjust the brakes as circumstances dictate. By glancing at display when I brake, to see how the trailer is responding, gives me real time ability to adjust as needed.
by: David 01/14/2023
Not my first Tekonsha and it won't be my last. Their brake controllers are flawless and easy to install, especially with a Tekonsha adapter. Installation took me no more than 15 minutes. The hardest part is figuring out where to mount the controller on my dashboard.

- Tekonsha TK90160 Primus Brake Controller isn't Reading TrailerThe NC error code means that the brake controller isn't 'reading' the trailer.

If the pins or sockets show white or green corrosion, you can try cleaning it off with sandpaper or a small file, but if the corrosion is severe, there's a chance that the corrosion has spread to the interior of the connector where...
view full answer... - Wiring 2006 Honda CR-V for Towing Trailer With BrakesFor starters, you'll need to determine if your CR-V is capable of towing the trailer you're planning on using. In my research, I found that the CR-V has a 1500 lb towing capacity, so the trailer you want to tow will need to weight less than that. I'd urge you to consult your owner's manual or your Honda dealer to confirm that capacity for yourself. If you're wanting to tow a trailer equipped with electric brakes, you'll need to install a brake controller. I'd recommend a proportional style...

If one gets hot only when your brake pedal is pressed, then you can connect the RoadMaster Transmitter # RM-9420 to that. Otherwise, your best bet would be to locate the trailer brake controller connector and tap into the stop light switch that way. If you check up under your dash to the right of the steering wheel (basically behind that center panel)...

view full answer... - Recommended Brake Controller for Towing Pop-Up Camper with 2002 SilveradoThe Tekonsha Primus Brake Controller you mentioned, part # TK90160 would work very well for you and would be the perfect choice for your pop-up camper. The primary difference between the Primus and the Prodigy P2, part # 90885 (which would be the next step up) is that the P2 can be mounted at any angle as long as it is parallel to the direction of travel, while the Primus must be mounted between level and 70 degrees above level.

To do this, you simply unplug the connector at the back of the brake controller for about 20 seconds and the reconnect the connector to the brake controller. I spoke with my contact at Tekonsha and he told me that this can happen when the vehicle batteries are replaced, especially if the brake controller is left connected in the vehicle while the battery is being replaced.

The wires are really hard to find in the engine compartment, on a 25 year old vehicle they're likely covered with road gack and grease. If you have some existing wiring under the dash from the previous owner, you can use a circuit tester like # PTW2993...
