Installation of Tekonsha T-One Connector

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies and some interior paneling to access this harness. Once you've plugged in the T-connector, run the body harness up to your car battery and connect the wires per the included instructions.

T-One Connection Location Points Behind Tail Lights

Once installation is complete, the 7-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.

It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 7-pole connector itself - to help prevent corrosion.

ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's 3-wire system need to be combined so they are compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.

With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Installation of Tekonsha Brake Controller Adapter

This adapter plugs into the 4-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.

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.

2018 Chevrolet Volt

I feel like the guys at etrailer are doing a great job at customer service, and go above and beyond as far as the videos they make for products they didn’t even produce. The original manufacturers instructions for this product leave a lot to be desired.
Let’s start with the required tools list: Tester or Volt Meter (the instructions never reference it again, but it will be needed to find the correct green wire at the “vehicle body harness connection point”. Or even better, a picture of the wire behind the passenger front tire:
(See photo of body harness connection point)

When it’s time to run the 18 gauge blue wire through the “side cargo trim panels”, I couldn’t find a grommet underneath the vehicle that led up the side of the vehicle, so instead, I drilled a ¼” hole in the light pocket (see Figure-1 below), added a small rubber grommet, and using a fishing wire, pulled it up to the “door electrical harness” (see Figure-2).

If you use the provided wire-tap, at this location, you will now need an extra one for the “vehicle body harness connection point”, as the kit only comes with one.
Lastly, if you watch some of the videos, you’ll see they run the power wires up front, and into the engine bay, but don’t really show exactly where they come up, but it appears it’s right next to the exhaust (which would not be good). The instructions say to “follow existing wires/to post underneath hood”. Rather than connecting at the battery, I ran my wires through the grommet at the bottom of this area (see next photo), and connected to the Battery jump post instead.
(See photo)

This is a great product, and well thought out, it seems they (Tekonsha) could have gone just a little further on the instructions for those of us who don’t do this every day.

The brake controller works great! Dont get to pull a travel trailer as often as Id like, but when I do, it functions like it should.


Easy to to order and accurate. Good installation instructions!


Never actually towed anything with it as I got it for a bike rack but it installs and is every bit like the factory full load hitch including hiding it behind the removable hitch panel.



Have got around to some light towing with it. Cannot complain at all. It does what it is supposed to do.

2017 Dodge Durango

Directions very tech support from etrailer and manufacturers tech support is closed on on the weekend when most people work on their vehicles.


Everything i need to hook up my lights and electric brake assistance. I bought a 4 way adapter for a utility trailer hook up. I had this installed for me at my local U-Haul store. I wasn't going to attempt it lol. Leave it to the professionals. I'm very happy with this purchase, Thank You!

2017 Dodge Durango

The product was as descripted and prompt upon delivery. Works flawlessly with the 2017 durango gt.

I installed the Mopar hitch at the same time as this wiring harness and it took longer then I had expected.

I prefer not to use the wire taps so I removed some insulation from the signal wire in the hatch and twisted the blue wire around it. Wrapped it up with electric tape and called it good.

For the front green signal wire above the passenger front wheel well. I didn’t want to expose that to the elements, so i chased it to the fuse block in the engine bay and back probed it there.

This kit came with all the necessary materials needed, and of course use dielectric on the connectors for longevity.

2018 Dodge Durango

Overall product works flawlessly. The only complaint I have was with the installation instructions. If I didn't find a guide online that someone wrote up I would have never been able to complete the installation. In the instructions it tells you to hook a wire up behind the forward tire fender well on the passenger side to a connector that doesn't exist. The actual location is inside the vehicle on the driver's side near the rear hatch other then this it was straight forward with following the guide found online.


Arrived on time with full very clear instructions for installation of everything. Only thing I was disappointed about was the brake controller had come out of the package during shipping and was just floating around on the box. Watched several of the installation videos before I even received the products. So very helpful. Keep up the great work

2018 Dodge Durango

I got exactly what I needed and a great price for my 2018 Dodge Durango. The installation videos made it easy to install!


Phenomenal support! Was able to follow the video and do this myself. Not a mechanic, not a construction guy…just a dad trying to do a few things here and there to save money and this was an accomplishment I am proud of!


Our order was shipped very quickly, and arrived in excellent condition. We received a phone call after we submitted our online order to confirm the order. Received an email to advise our order was shipped, and we also received an email our order was successfully delivered. Great communication!


Easy Install and holding up well after a year of use in New England

  • Trouble Locating Green Wire To Connect To 12 Gauge Blue Wire In Tekonsha 7-Way Harness
    For the 12 gauge blue wire connection you will not have to remove the liner completely. You will only need to remove enough of the screws to allow you to be able to find the connector inside the fender well. Many have trouble finding this connection and if you wish you can actually run the wire another way. The wire is simply the factory brake output. A simpler way of running the wire would be to run it into the vehicle and connect it to the blue wire on the brake controller harness....

  • Does Tekonsha 7-Way # TK22113 For 2017 Dodge Durango Activate Brake Controller Wiring
    Yes, the Tekonsha 7-way kit part # TK22113 that you referenced does enable the brake controller wiring circuits of your 2017 Dodge Durango as it completes everything.

    The vehicle connection wire isn't as easy as just saying the green wire that is closest to (blank) is the one you are looking for. Each of the green wires need to be tested to determine the correct wire function using a circuit tester or voltage meter. Once you either connect a brake controller and hit the manual override on the controller (or if you don't have a controller sending 12V power down that pin location), you will be able to put a circuit tester on the green wires of that...
