Installation of Tekonsha Brake Controller Adapter

Junction BoxBrake-Control Adapter Port

This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.


To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.


This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

In the world of electrical accessories, it's very common to find "some assembly required" and the vendor expects the end user to figure it out. This is not that experience. If you can work a waffle iron, you can use this harness. There is no excuse to run without the electronic controller that you know you need. Paige this up with the Tekonsha P3 for minute control of your braking and much safer towing. Remember the hot rodder's creed - don't make or go if you can't make it stop! 724710

2006 Ram 2500

I have this product on my 2006 Suburban 1500 LT and my wife's 2005 Honda Pilot. I just bought a 2006 Suburban 2500 and the new brake controller will on on this vehicle. I also bought a control cable to make it easier to install the Tekonsha P3 controller. This was a wire pigtail included with the controller/ Since I had trouble routing the cable from the center console to near the brake area, I cut the connector on the controller side of the pigtail leaving the factory connector on. Took the pigtail shipped with the controller and routed the loose wires thru the smaller openings and spliced the two cables together and the jobs done. Worked GREAT!!!!!!!!! The only down side of the installation the GM cable no connecting instructions came with it, But with that said the etrailer Site did have a picture where the GM cable was to plugin at. 727062

  • Troubleshooting No Power to Blue Wire When Brake is Applied on the 2007 Chevrolet Silverado Classic
    Not to worry, this is a common issue and I will be happy to help you get the blue wire working. The blue wire is the output wire from the brake controller. It is only activated when the brakes are pressed or the manual override is activated. There has to be constant power on the black wire and on the red wire when the brake pedal is pressed for the blue wire to function properly. If you are using a proportional brake controller like # 90195 and are only testing the blue wire with...

  • Best Brake Controller Recommendation for a 2014 Chevy Silverado 1500
    For a brake controller 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. As far as we are aware the 2014 Chevy Silverados all came with factory 7-ways at the rear of them. Which in that case all you would need to install the brake controller would be the # 3016 harness. I attached an install video for these two products to the right for you to check out as well. If you...

  • Wiring Harness Needed to Install Tekonsha Voyager Brake Controller on 2004 GMC Yukon XL
    If your 2004 GMC Yukon 1500 already has a factory 7-way installed, you will just need the Tekonsha Wiring Adapter # 3015-P to install your Tekonsha Voyager Trailer Brake Controller # 39510. One end of the adapter will simply plug into the brake controller and the other end will plug directly into the junction box behind the dash of your Yukon XL. I have attached some video demonstrations of this harness for your review.

  • How to Wire a 2010 GMC Yukon XL for a Brake Controller
    Yes, you will need to connect two wires under the hood of your 2011 GMC Yukon XL to wire a brake controller to your vehicles brake controller circuitry. To attach those wires to your vehicle you will need a Zinc Plated Hex Flange Nut - M6, part # 185916, and a Zinc Plated Hex Flange Nut, part # 185917. I attached an FAQ article on how this is done below for you to check out, as well as the video that you watched of the brake controller being installed on a 2011 Chevy Silverado that you...

  • Brake Controller and Install Harness Recommendation for a C5500 Motorhome
    The controller would need to be hardwired to your C5500 motorhome as it would not have a harness under the dash using our Brake Controller Installation Kit, part # ETBC7. Due to the fact that your motorhome is longer than the usual passenger vehicle, you'd need an extra length of wire, probably about 20 feet. The wire is sold by the foot as part # 10-2-1. I have linked you to instructions for the ETBC7 kit. I would recommend an easy to use, reliable proportional controller like...

    On your 2014 Chevrolet Tahoe with tow package there is no under-dash connection port for a brake controller but all the wires are already run. For a 2015 model year Tahoe there is a quick-connect harness, part # 3016. The P3 # 90195 includes a pigtail harness that plugs in to the back of the controller and the four wire leads from it will connect to your vehicle wiring.

  • Installing Draw-Tite Brake Controller On 2005 Chevrolet Silverado
    I recommend using part # 3015-P to easily install the brake controller. You just cut off the black connector on the adapter and wire it to the matching colors at the back of the brake controller. The other end of the harness plugs into the junction box located under the dash to the left of the brake. I have also attached some helpful articles that explain brake controller installation and troubleshooting you can check out.

  • Is a Brake Controller Needed on a 2010 GMC Yukon Denali Towing a 6,000 Pound Camper
    Some trucks now come equipped with factory brake controllers. Ford has been doing it since 2005 and GM started in 2006 or 2007. Your Yukon Denali may have come with an integrated brake controller. I would check with GMC to see if your Denali was built with an integrated brake controller. You should be able to call in with the VIN. If your Denali does not have an integrated brake controller, I would certainly add one if the camper is equipped with brakes. It will save wear and tear on...

  • Brake Controller Does Not Power On After Installation on a 2004 Chevy Silverado 1500
    Chevy trucks like your 2004 Silverado 1500 are known to require some additional connections under the hood to make a brake controller fully functional. We have a help article that covers exactly this which I have linked for you. The red wire with the ring terminal on it that you found goes on the stud at the back left of the power distribution box nearest the green 30 amp fuse. This is power to the brake controller. I have included a picture that will help. It is B in the picture.

    If the trailer you plan to tow has electric brakes and you want them to work, you will need a brake controller for your 2005 Chevy Silverado. The wiring harness you found is possibly for a brake controller. If it is, it will plug into a port underneath the dash.

    From what I was able to find, the 2008 GMC Topkick 5500 does not have a port to plug in a brake controller wiring harness. A brake controller will have to be hardwired into the vehicle using a 4 and 7 Way Installation Kit, # ETBC7. Usually, this would require the installation of a 4-Way wiring harness first that would then plug into the back of the ETBC7. However, there is not a 4-Way harness available for the Topkick, so you will need to clip off the 4-Way plug on the ETBC7 and hardwire...

You will connect the brake controller wiring with the vehicle wiring already present under the dash.

    Your 2012 Chevy Silverado is pre-wired for a brake controller but there is no plug under your dash for the connection of the controller. Instead there are 4 blunt cut wires there that you will need to hardwire to the Prodigy P2 part # 90885. The install video link I attached shows exactly how a brake controller will install in your truck. The truck in the video is a 2013 model but the process would be the exact same.

  • Trailer Brake Controller Wiring Harness for a 2003 Chevy Silverado
    It sounds as if you might have the wrong wiring adapter. The wiring adapter for the 2002 and 2003 Silverado will fit either vehicle, but the order in which the pins are wired is different. Therefore if you have the incorrect one, it will still plug in, but will not work correctly. For the 2003, you would need part # 3015-P, not the 3025-P which is for the 2002. This can easily be verified by using a circuit tester like part # 40376 on the red wire exiting the rear of the controller....

On the brake controller, white is ground, black is 12 volt power in, red is input from the brake switch, and blue is output to the trailer brakes.
