  • Haul a trailer only occasionally or mostly for short stretches

No, if you:

  • Have a trailer with hydraulic brakes
  • Rely heavily on the manual override function - the slide on this has a tendency to stick
  • Are limited on mounting locations in your cab and don't want to lose any leg room

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 (sold separately) 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.

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.

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.

I was in a bit of a spot and needed a trailer braking system in a hurry for my 2018 GMC Sierra pickup. After looking around at all the local automotive shops and part stores in the area... I was at my wit's end as no one that I spoke with had any information as to whether or not the unit they had would work for my truck. So I jumped online as it was getting down to crunch time and I needed the unit as I was to pick up the travel trailer and a couple of days. I went online and found etrailer.com After very little research and a quick phone call to tech support... they knew exactly what I needed along with the adapter cord that plugs right into the fuse panel. It took me all of 10 minutes to install the unit and it works phenomenal. Also due to the amount of time I had to get the unit and get it installed they expedited the shipping and I had it the next day. These folks know exactly what they're doing and what you need and will not disappoint. I have never had an easier and more pleasurable installation of an aftermarket product. I cannot recommend them highly enough. Thank you very much again a very satisfied customer. I purchased the Primus IQ which is a proportional braking system and again it came with a harness that went right into the fuse panel in my truck. The instructions were easy to follow and a unit works very very well. As I said 10 minutes to put it in at the most. Great job guys thanks again.

I actually transferred this trailer braking product out of my 2018 GMC pickup and moved it into my 2021 GMC pickup all I had to do was change the wiring harness which I picked up from etrailer.com and the braking system and controller Works phenomenal and continues to work for me for the price of replacing the wire harness between the controller and the fuse block behind the dash. The instructions were simple and again the breaking product works excellent

Tekonsha Primus IQ trailer brake controller worked as described. Excellent product. Installed on 2020 GMC Terrain. *As a side note I am a retired ASE Master certified technician, L1 small business owner for over 30+ years. Extremely familiar with wiring systems properly. What WASN'T GREAT was etrailer's 3 attemps at technical support during the original installation. In the end, me contacting the Tekonsha technical support not only got me the answer, the specific wire color and terminal and a PDF emailed to me by the manufacturer. etrailer didn't even try to contact the manufacturer which was easily accomplished. I had to instruct and link etrailer technical support to Tekonsha key personnel and suggested the protocol that I used. The issue was that the controller's brake sensor wire could not be tapped into multi-wire brake switch, as 3rd brake light is controlled by a BCM computer. The module location and the output wire needed to be identified so that a tap could be provided.

Thank you for your review and I apologize about the trouble you had to go through to get the answer. Attached is one of our expert answers on the matter:

I installed this electric brake control on my 2015 Subaru Outback with Eye-sight feature. The brake switch on the car has 5 wires connected to it, so I had to go to the dealer and have them tell me WHICH of the 5 is the specific wire I needed to correctly connect the brake control unit. Everything else, mounting and connecting all the rest of the wires is a snap. Seems like it works properly, although after I installed and connected the controller, I drove the car with the trailer in tow in order to set up the controller per the instructions given. It said the controller should at some point apply the trailer brakes fully, as if to stop the trailer quickly, but I never got it to do that; although I could tell the brakes were being applied. I suspect that this is due to the very small gauge of the wire coming out of the Subaru brake switch not being as heavy gauge as the rest of the wires used to connect the electric brakes controller. But as I said, it did seem that the electric brakes on my trailer were being engaged. It is fine for me, since I will only be towing my sailboat on flat ground going from my house to the boat launch, once in and once out for the season.

Still loving it, & recommended it & etrailer to a friend. He bought one & is very happy too.

Works as intended, but the plug on the back of the controller is a loose connection. Sometimes I would go to brake and find that I had no trailer brakes because the controller lost power. After a wiggle it would start to work again. I was able to shave the Molex plug a bit and now I don't have any problems with it.

Thank you for your review. I have not heard of that problem. I would have used some electrical tape.

This is a great controller. I have a small single axle trailer and it was easy to set up and adjust. The only thing I had to do custom was to install some small wood shims between the bracket and the underside of the dash so that the unit would be level when mounted. This was due to the fact that the underside of the dash was curved and sloped. I like that I can easily disconnect and reconnect the unit when not in us, because the bracket stays mounted to the dash.

Have had the brake controller for one year now. Traveled 9,000 mmiles with a 5,000 lb. travel trailer and can say this was the best addition to the truck for towing. It was easy to install and works flawlessly. Neglected to plug in the seven pin connection once and really noticed the difference in a panic stop situation that occurred. I can definitely recommend this trailer brake controller for towing.

I bought a new truck and needed a new trailer brake controller. I wanted something that didn't have the jerk everytime I braked with my trailer(26 foot KZ Sportsmen). After searching on line and reading different reviews I settled on the Tekonsha PRIMUS IQ . It was easy to install and set up. I really like the progressive brake control. The more brake I call for the controller applies more brake. Gone is the jerk I would get with my other controller. No matter how I set the old controlle I would get the jerk and it got worse with a higher brake setting. No issues and would buy it again.

The PRIMUS IQ has been working perfectly. all jerking issues are gone. I have not touched it since my final setting.

2013 Yukon Denali 6.2 awd. I followed the install video from your site and it made installation a breeze which was the biggest concern. The controller works flawlessly, Simple set up and easy adjustability. Great experience from start to finish. Recommend!!

1 year follow up and I’ve had zero problems with this unit after towing roughly 5,500 - 6000 lbs. Works like a champ.

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.

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.

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.

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.

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

Very happy with the proportional controller. When braking I don’t notice that the trailer is behind me because the controller works so well. I installed the Tekonsha in a 2012 Tundra that I bought used. It had a Tekonsha style connector but the brake controller had been removed by a previous owner. There was an installation note in the box. It said that the red wire should be 12 volts positive when the brake is applied and must not be grounded when the brake is released. If the red wire is grounded and the brake control is operated manually it will destroy the control. I checked my connector because I had not installed it my self. The Red wire was grounded when the brake pedal was released and 12v when depressed. I removed the cable and found that it is pin for pin the same as the cable listed for the Tundra. The easiest way to fix that problem was to put a diode in series with the red wire. (put the bar marking on the diode towards the control and check with a meter or test light) The directions said to wire directly to the brake pedal switch but that is a messy way to do it.

- TK90160

No complaints. Easy install with the adapter harness. Plug and go. I installed this in a 2020 RAM 1500 and gotta say, difficult to find an under-dash location that doesn't interfere with your legs. A lower profile controller could have helped or more room from RAM ... blame whoever you like there. I put mine under-dash on the left - just seemed better.

i was shocked at how easy it was to install. the product was great quality, and engineered to plug right in to my vehicle. i love this company.

Bought one for the little truck to pull the camper. It works so well I bought one to replace a older voyager unit in the truck that pulls the race car trailer. Very happy with it.

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.

- TK90160

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.

    To begin, you will need to install a working 4-pin connector to access the taillight circuits in the van. I'd recommend using # 118551. You will also need a brake controller installation kit # ETBC7, which would include all of the wire, 7-Way connector/adapter that plugs into the 4-pin connector, circuit breakers and wiring connectors to complete the brake controller installation. You'll also need some extra wire, part # ETBCXW due to the length of your vehicle. For a brake controller...

  • Installing an Aftermarket Brake Controller on a 2021 Ford F-150
    Installing an aftermarket brake controller, like the Tekonsha Primus IQ # TK90160, is definitely possible. That being said, not all of the 2021 models have the power run to get the controller up and running, so you may need to add # BRK-ELECKIT. This will add the power needed and is not very difficult to install. Especially since your vehicle will have a factory port under the dash. The Tekonsha # 22292 will plug directly into this port and then directly into the back of the # TK90160. To...

    If you wanted to use the Tekonsha Primus IQ part # TK90160 on your 2020 Jeep Wrangler then you would need to cut off the end of the plug under your dash and wire in the one that comes with the brake controller or you could use the Curt Custom Wiring Adapter part # C51459 and cut off the brake controller end in favor of the one that comes with the brake controller so no vehicle slicing is required.

  • Is Tekonsha Primus IQ Trailer Brake Controller Compatible With 2019 Ram 1500 Classic
    Yes, the Tekonsha Primus IQ Trailer Brake Controller # TK90160 with Plug-In Wiring Adapter # 3024-P is compatible with your 2019 Ram 1500 Classic. Though I'm not 100% certain what you mean by not being able to move without using the brake pedal, it sounds like your brakes are sticking. If so, it just sounds like the manual override may be on, either accidentally or just stuck so I highly recommend checking that isn't the issue.

I've attached a photo to help. This will help you to easily connect your Primus IQ # TK90160.

  • Tekonsha TK90160 Primus Vs. Curt C51120 Discovery Brake Controller for a 2014 Mitsubishi Outlander
    I'd have to respectfully disagree with your dealer. Except in very special circumstances, I'll always recommend going with a proportional controller like the Tekonsha Primus # TK90160 versus the Time-Delayed Curt # C51120 Discovery. A time delayed brake controller will always send the same amount of power to the trailer brakes according to how you've set the controller, you can also adjust how quickly the voltage is delivered to the trailer brakes. This means that the trailer brakes...

  • Will the Primus IQ Brake Controller work with Electric Over Hydraulic Brakes
    I have a solution for you, but the Primus part # TK90160 will not work with electric over hydraulic brakes. For a brake controller that is compatible I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes.

  • Brake Controller is Tripping the Electronic Stability Control Light on a Chrysler Pacifica
    This can be caused by a few different things. If your 2017 Chrysler Pacific did not come pre-wired from the factory, it is most likely wired incorrectly. The red wire coming out of the controller should be connected to the stoplight switch and is most likely where the issue is. The way to test this would be to remove the red wire from the one it is spliced with, and run the manual override again. If it does not trip the traction control light, which is what that light is, then you will...
