Tekonsha Trailer Brake Controller

  • Electric
  • Time Delayed Controller
  • Tekonsha
  • Indicator Lights
  • Up to 2 Axles
  • Under-Dash Box
  • Dash Mount
  • Automatic Leveling
  • Up to 360 Degrees

Easy-to-use brake controller activates your trailer brakes electronically when you engage the brakes in your tow vehicle. Set braking intensity to your preference and towing application.


Features:

  • Brake controller activates electric trailer brakes (sold separately)
    • Signal is sent to trailer brakes when tow-vehicle brakes are activated
  • Adjustable output control lets you determine the amount of braking force
    • Set to maximum when you travel through hilly terrain with your fully loaded trailer
    • Back off the power output when you tow a lightweight trailer
  • LED indicator on front of unit
    • Green light indicates that brakes are connected
    • Color changes to orange and then to red as the power output increases
  • Built-in manual override
  • PowerTrac can be used with trailers that have up to 2 axles (4 brake assemblies total)
  • Mounting bracket and hardware included
    • No need to mount level
  • Additional pigtail harness (sold separately) is required for complete installation
    • For some vehicle-specific applications a plug-in, vehicle-specific brake-control adapter (sold separately) can be used to further reduce installation time


Specs:

  • Dimensions: 3" wide x 5" long x 1-1/4" tall
  • Limited 5-year warranty


Unlike pendulum-style controllers, which react to the inertia that is created by your tow vehicle slowing down, the PowerTrac applies your trailer's brakes when the brake pedal in your tow vehicle is engaged. The trailer brakes will be activated with an intensity set by you. This output (amount of braking power) is adjustable to suit your preference, as well as road conditions, type of trailer and load. You can also apply the brakes manually with the integrated override.


Because inertia plays no role in the functioning of this controller, you do not have to mount the unit at any particular angle. As a result, mounting options are nearly limitless. After mounting the unit, hardwire the end of the pigtail harness (sold separately) directly into your vehicle. 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. To transfer the PowerTrac to another vehicle or to remove it for storage, just unplug the unit and remove it from the mount.


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: For vehicles without brake-control wiring adapters, a 20-amp circuit breaker (9506P - sold separately) is required.


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 PowerTrac brake controller.

Worked out perfectly for me, super easy installation with adapter harness. Work's flawlessly, easy one hand gain control with control's on front. My truck had nice cubby it fit in so out of the way and seamless look. Thanks for a great product and service.

I really like the simplicity of this plug n play brake controller. I would give it 5 stars but it adjusts with a wheel/dial without any graduations on it so it’s hard to just set the gain without testing the brakes. That’s probably not really a bad thing but not as convenient as other controllers.

After a year were still going strong without any issues! It works great.

We have a Honda Ridgeline and needed this for our camper trailer. It was nice ordering the specific plug in wire for the Ridgeline and therefore eliminating hard wiring, just plugged it in. It was rough getting to the factory plug under the dash by the emergency brake petal switch. My hands are not small enough, ha ha. But success was had. Plugged into the controller and mounted it and u-wall-a. It works the way it is suppose to, I like that. A good quality unit that does what it is suppose to. thanks.


Comments
After a year, I dont even think about it being there. I love that. It works the way it should. When traveling with our trailer, I might adjust the controller slightly but that is it. . . .thanks etrailer and Tekonsha for such great products and service. . .you rock. . . .jim

Very happy with this product. It fit nicely in my truck and plugged right into the factory wiring harness. Total installation time was under an hour. Easy to adjust, and works perfectly with my 5th wheel trailer. I simply pulled out the little storage cubby from the dash, cut the back off, slid the controller in, bolted it together, and stuck it all back in the dash. Looks and works great.


Comments
Still great after a year. I tow a bunch of different trailers. Adjusting between trailers is a snap. Ive received lots of positive comments on how nicely it fits in the truck, like it was made to be there.

One year later I'm extremely pleased with this purchase. I often chuckle when I see stock hitches and the whole thing is visible while mine is neatly tucked under with everything hidden except for the 2" receiver. 10/10 have recommended etrailer on many occasions to friends and family for their service and know-how. Since installing my hitch I towed a pop up camper 1500+kms and do frequent trips to the dump or my local dirt and gravel yard for supplies. Love it!

I have a Toyota Tacoma (06). I had the controller installed in less than five minutes. One minute to gather the tools: drill/bits, screw driver, and tape. I thought tape would be helpful to hold the ground screw to the driver given the tight are under the dash. One minute to drill the ground hole. One minute to install the ground screw. One minute to plug in the cables and fish the wire under the stirring wheel to allow for the controller to be mounted in the storage area found on Tacoma trucks dash. I guess I was wrong. It only took four minutes. I did not need to put the tools away I was off to do other projects. I rate the product as good because I have not tried it on the trailer yet.


Comments
Today I used the controller out on the road, it worked great. Now I give the product a SIX star rating. Its better than a five star rating because of the reasonable price and installation of the product. Good job etrailer. Mike from Santa Fe.

The controller works fine. It takes a second or so for them to activate and release which can take some getting use to. I am going to look into a different controller that reacts instantly with my vehicle brakes.
Bill G - 06/04/2018

Thanks for your follow up on your PowerTrac Brake controller the delay that you are describing is common with a time delay style of brake controller. A proportional brake controller will be more responsive than a time delay, and will brake in "proportion" to your vehicle braking. My recommendation would be for the Tekonsha P3 # 90195
Tekonsha Prodigy P3 Trailer Brake Controller - 1 to 4 Axles - Proportional
$151.74
, since it does indeed offer top of the linke diagnostics, as well as the option to program different trailer settings. I have also linked our current offerings of proportional brake controllers for your reference.

Easy to install in my Toyota-Tacoma 2012. I pull my Travel Trailer and this break controller worked very well and with just a little bit adjustment. Also this item was shipped very fast.


Comments
I just installed this on my 2010 Tacoma, which was very easy. I hooked up a new trailer and I noticed right a way the brakes seem to pulse. You can see the LED flicker between red and green that appears to be synced with the brake pulsing. Does yours behave similarly? This is my first trailer and brake controller so Im not sure if its normal or not.
-- comment by: Quincy - 04/02/2014

That is not normal operation. There are two likely culprits: First, a weak or loose connection to the brake switch wire. Double check that first so the controller can positively know when you are applying brakes in the Tacoma. Second, Toyotas are known for finnicky electrical grounds. If you didn't when you installed it, run the ground wire for the controller to the negative terminal on the battery. If it is grounded to the body, the controller may not be getting sufficient ground so the brakes start to engage and the ground cuts out, and it does this over and over resulting in the pulse.

Perfect brake controller For moving our equipment trailer With our three-quarter ton truck. I prefer brake controllers that do not have a delay or inertia based.

Thanks to etrailer’s video “Trailer Brake Controller Installation - 2004 Jeep Grand Cherokee”, the installation of a Tekonsha PowerTrac controller on my 2003 Jeep was very straight forward (and I’m not a car guy!).

The control works great. Nice incremental application of wheel from nothing to hard on! Led light goes from green to red also in incremental degrees. Installation was a snap in my 2008 F150 with tow package. Just Plug in the control clip and the other end in the terminal above and to the right of the computer check terminal. Rather than have it below my dash I opted for the cove below the lighter. Etrailer did a nice job of getting out to me right away and kept me informed where this was at all the way to my door. Good Job!

This controller works very well on my 2007 Honda Ridgeline. I don't tow often so this is just right for me. The only down side is that my knee hits it sometimes, but that's not the controller's fault. There's just not many good places to mount it on the Ridgeline.

Produts were easy to install and works good. Some of the steps in the installation instructions from etrailer can be skipped if you get the controller adapter to plug controller into oem harness under dash. Ford trucks have brake controller connector prewired reguardless with/without factory tow package.

  • Should the Light on the Pod Brake Controller be On All the Time with No Trailer Connected
    When no trailer is connected the light on brake controller # 39523 will either be flashing or off. If it is green all the time with no trailer connected that indicates a short to ground. This normally occurs when there is corrosion on the pins or where the wires attach on the trailer connector. I have included a link to the instructions that include a troubleshooting section. I have also included a link to our FAQ article on troubleshooting brake controllers for you.

  • Does the Tekonsha PowerTrac Brake Controller Need to Be Leveled for it to Function Correctly
    Since the Tekonsha PowerTrac Electronic Brake Controller # 39523 you referenced is a time delayed controller there is no specific orientation that it needs to be in for it to work. In other words, no, you do not need to level the controller in any way for it to work. As long as it is wired correctly the controller will function like it should. I would recommend you have it orientated so that if you needed to reach the manual brake override lever it would be easily accessible. I attached...

  • Finding the Wire for the Cold Side of Brake Switch on a 2001 Chevy Express Van
    To find the cold side of the brake switch on your 2001 Chevy Express Van you will need to use your circuit tester to test the brake switch wires. The van key might have to be turned on for this test. You will need the wire that shows power only when the brake pedal is pressed. When you release the pedal it should not have power. And it should also not have power with the headlights or turn signals on. On newer models, 2003 and up, the cold side wire is a white wire so test that one first.

    Many trailer brake controllers like your Tekonsha PowerTrac # 39523 will actually send short pulses of power back to the brake output pin on the 7-Way even when the vehicle is off. This is essentially the controller's way of checking for a connection with a trailer.
