Use this pigtail wiring harness to quickly and easily transfer your brake controller between vehicles or to replace a lost or damaged wiring harness. Works with most Tekonsha and Draw-Tite brake controllers.


Didn’t take any time to hookup, just have to pay attention because wires are different colors on the Tahoe than the brake controller. The vehicle wires have a paper tag that tells which wire goes where as does the instructions on the controller. I can confirm the wiring harness and Takonsha P3 will work on a 2023 Tahoe!


This kit had everything I needed. With the help of your videos, I was able to install it myself on my 2013 Toyota Highlander. I did have to drill through the firewall though. For that you will need an a sharp drill bit, a grommet and some silicone caulk.


I installed them on customers trailers and they haven't complained so I guess that's your answer.


Shipped and was received quickly and the quality is good.


I ordered these parts to replace a controller that went bad in one of my work vans. The etrailer website was very helpful with pictures and descriptions of the various controllers that would work for my vehicle and suggested i order an optional wiring harness, which i did. The pricing was good. Also i didnt ask for it, but after i ordered online, the sales dept upgraded the shipping at no additional cost and i got an emails when it shipped and when it arrived. Overall im very pleased with etrailer. Thank you

There still working
Francis - 11/12/2018


Perfect. It is just what I needed.


This is the wiring pigtail that the brake controller SHOULD have included to begin with! 35 inches of wire to work with versus 8 inches. Exactly what is necessary to do a neat and flexible wiring job. Thank you E-trailer for offering this. Shame on Tekonsha for not including this. I suggest that etrailer offer this as a frequent add-on to provide the installer / consumer with flexibility of installation. If I had known I would have purchased with my initial order and saved the shipping cost.

Sal D - 02/22/2020


Both of my items (trailer wire harness and trailer axle) came in perfect condition and right on time. I couldn’t be happier with etrailer! They also have a great selection and you can’t beat the prices.

Thousands of miles later the axle is still working great! I highly recommend it as a replacement axle, my trailer had a lower pound rear axle and was bent after a few years of use, the axle from e-trailer was easy to install and has been great!

Fit my brake controller perfectly just what I expected great price


etrailer was the best company I've ever dealt with online. I told Melinda E. what I wanted to do and she put together a package of the hitch, wiring harness, and brake controller for me.

Everything installed perfectly and I just got back from towing a 10,000 lb trailer over 600 miles.

I have already recommended etrailer to friends and I can confidently say they are the ONLY place I'll buy trailering equipment from.

Thanks Melinda!!


Well made product. Thanks!

No problems at all since installing.
Jerry C - 03/04/2022


I didn't get this to replace a bad connector but to install my Tekonsha Prodigy P3 into another truck. I have more than one truck I tow with so using this harness and the mount bracket (part # 5906) I'm able to move my brake controller to whichever truck I'm using to tow with. The bracket and harness are MUCH cheaper than buying another controller and the bracket is made to be able to quick release the controller. This ability to move the controller from truck to truck is one of the reasons I chose the Tekonsha Prodigy P3 brake controller in the first place.


Purchased to compliment my Draw-Tite I- Command Proportional controller (P#5535). Made for easy install in my 97 Ram 1500. Used with the ETBC7 Wiring harness.


Great price on a pigtail harness for the Prodigy brake controller! This particular item has longer wires than a similar harness listed on this site and also includes crimp connectors as well. The best part was that it costs less than the regular harness.


It was very easy to install all the instructions were there.


I needed to be able to move my brake controller between vehicles. For a fraction of the cost of a second controller I was able to easily install a bracket and wiring harness in my second vehicle. etrailer provided good parts, great prices and fast shipping.


Had it installed and has worked great and have used trailer several times
a week. Never needed any adjustment or anything. great product!!

No problems and the trailer gets a lot of use hauling our tractor and side by side!
J. T - 08/20/2017


This wiring harness was exactly what I needed to install my trailer brake controller in my new van. Wire guage matched that of my van and also included connectors making it quick and easy. Etrailer does it again.


Was shorted a wiring harness for a break controller from another supplier so ordered it from etrailer. Original suppier finally sent the harness so etrailer was kind enough to let me return theirs for full price less original shipping. Thank you etrailer.


Completed the entire installation in about 15 minutes. I watched the etrailer [install] video for the installation and it was a breeze.

After one year of use, no issues and works as needed.

Works great!


Great brake controller. Easy install. Good costumer support. Installed in my motor home. 2017 Liesure Unity Murphy bed. Mercedes 3500 Sprinter. Mercedes dealer wanted over $800.00 to do install. I did it myself for the cost of Tekonsha voyager controller and pigtail wire harness. Plug and play as they say..


I bought this adaptor so that I could use the same Tekonsha controller for two vehicles. The install was easy and it has worked well. I'd recommend this to anyone who wants to do the same.


This allows me to switch my brake controller between vehicles. I used this as part of several parts to install hitch and brake controller on a 2017 Jeep Cherokee latitude v6. Parts used 118605, C13171, 6927, 7894 and ETBC7.


I didn't have to use this pigtail.

  • Can Brake Controller Not In Use be Simply Unplugged from Vehicle
    Yes, you can simply unplug the brake controller you have and it won't negatively affect anything else on your truck. Sounds like your problem is the controller malfunctioning or you have a short between the wiring of the controller on the red and black wires.

  • Brake Controller Adapter For A 2012 Volkswagen Touareg
    I have an option for you to connect a Draw-Tite brake controller to your 2012 Volkswagen Touareg however, none of which include a direct plug-and-play connection. we are currently not aware of an option to plug an adapter into the existing wiring harness without the process of hardwiring. In order to connect the Draw-Tite brake controller to your vehicle you will want the Replacement Brake Controller Harness part # 7894. This is a direct fit for all Draw-Tite brake controllers and only...

  • Installing a Tekonsha Brake Controller on a 2014 Porsche Cayenne
    You can use your Tekonsha brake controller in your 2014 Porsche Cayenne, however, there are not custom wiring adapters available for the Cayenne, so you will want to splice in a universal harness, # 7894. Installing a brake controller on your Cayenne using the factory brake controller wires can be a little tricky so I attached a help article that explains the installation process in detail. The installation covers all Cayennes from 2005 to present.

  • Is Harness Needed to Install Prodigy Brake Controller on 2010 Chevy Silverado?
    With a Prodigy brake controller, there is no need to use harness # 7894 because the controller has the wires already. To install the controller, you only need to find and access the wiring behind the dash under the steering column. I have attached a link to an install on a 2012 Silverado for you which details what you'll need to do.

    There is not a brake controller wiring harness available for the Mercedes ML series vehicles. You will need the Replacement Plugin Harness for Tekonsha and Draw-Tite Brake Controllers, item # 7894, to hard wire your Prodigy brake controller. You could just remove the ford connector from the wiring on the brake controller. Be sure to remove the right end. I spoke with my contact at Tekonsha and his advice is that you should take the ML Class vehicle to the dealer to have the brake controller...

  • Installation of Brake Controller on 2011 Chevy Silverado Where No Power Is Present on Wires
    It looks like you've got a 2011 Chevy Silverado, and it's likely that you just don't have power on the wires you've connected the Pigtail Wiring Harness # 7894 to on your vehicle. If you haven't already, you should test the power wire to see if it's active when you turn the vehicle on. There are two wires under the hood that have to be connected to make the tow package functional, one is the power wire to the brake control and the other is the battery charge line to the 7 way connector....

  • Brake Controller Recommendation for 2010 Chevrolet Silverado
    For your 2010 Chevrolet Silverado I recommend the Tekonsha Prodigy P3 Brake Controller # 90195. The P3 is a proportional brake controller that activates immediately and automatically adjusts the trailer's braking based on the deceleration of the tow vehicle. This brake controller performs continuous diagnostic checks and features an easy-to-read LCD display. The 2010 Silverado does not have a brake controller port, so they do not offer a harness for a quick plug and play installation....

    There are some steps to installing a brake controller on a 2014 Touareg that are different than a typical brake controller installation. Some of the needed parts will have to be purchased from your Volkswagen dealer. You may also need a 12V normally open relay. I have attached a help article on installing a brake controller on 2005-Current Tourage for you. If you need a replacement pigtail wiring harness for your Tekonsha Prodigy P2 # 90885, you can use the Tekonsha # 7894.

  • Wiring Adapter for Tekonsha Prodigy P2 90885 on a 2007 Yukon XL
    There is no direct plug present under the dash, but the needed wires are already run. You will connect the brake controller wiring with the vehicle wiring already present under the dash with the # 7894 that is included with your Tekonsha Prodigy P2 brake controller # 90885. I have linked a video of the brake controller being installed on a similar vehicle to your Yukon for your convenience.

  • Wire Harness Recommendation to Install Tekonsha Voyager in a 2015 Chevy Colorado
    Your 2015 Chevy Colorado is going to have the wires for installing a brake controller present under the dash. The harness part # 7894 would connect to a Voyager part # 39510 and would allow you to wire to those wires. If you check out the install video you can see how this would install on a similar 2015 Colorado as yours.
