Installation of Tekonsha Brake Controller Adapter

To install your electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.

The connector is located under the driver's seat. No hardwiring is required to install this adapter. After you plug it into the factory port, you simply plug the other end of the adapter directly into your electric trailer brake controller. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.

2022 Mercedes-Benz Sprinter

In case my first review posts, after an unsuccessful online chat with someone at etrailer, I called them and spoke with a very nice and knowledgeable man (unfortunately I didn’t catch his name). He walked me through the subtle differences between the 2nd generation Sprinter van 7-way factory plug and the 3rd (current) generation van which I have and via telephone I was able to get the Tekonsha adapter harness connected. Thanks etrailer!


This harness fits more years than noted, so long as you have the green factory connector under the driver seat. I thought shipping this item would take several weeks but E-Trailer had it out in just a couple days. A quality product that worked perfectly and was easily installed.



So glad I purchased. So little effort to install and it allowed the Tekonsha controller to work while pulling a trailer in Alaska. Very easy mod to our 2012 MB Sprinter.


This brake controller was so simple to install with help from etrailer.
It unit operats the electric brakes on my trailer great and I love that I can adjust the braking power from inside my motorhome.


Works great, following instructions and installed the trailer controller. Not all defaclut to install and the hardest thing was getting a 66 Year old kid in position to install it under the dash! I don’t bend as easy as I use too.


Hello Alex. I appreciate the follow-up on my brake controller and wiring for my Sprinter van. The wiring was plug and play. It was s little difficult running the wires, but I got it. Again the wiring was plug and play along with the brake controller. I plugged it in and it immediately worked. I haven't towed the trailer with it yet, but will soon. Thanks again for the information on what to buy. You made the project so much easier.


It's always a great day when you can plug and play! No cutting or splicing wire with this kit. Works great!

Perfect set-up to add brake controller to my sprinter van

2016 Mercedes-Benz Sprinter 3500



Great service !!!!!


Makes life easy


The adapter worked as expected. Plug and play. Routing was difficult but that iz a van specific issue.

2021 Jeep Wrangler

Installed this in my 2020 Winnebago View (a 2019 MB Sprinter cassis and cab). I'm using it with a Brake Buddy Stealth controller. Routing it to the dash has a chore, but there are how-to videos on [online]. Most will simply lop off the Tekonsha connector and splice it directly to the pigtail wires on the Stealth controller. I chose, instead, to purchase a mating connector and add THAT to my controller, making the setup compatible with other popular controllers and removable without cutting wires. The Sprinter is pre-wired to "always hot" positive power, which means that you will always have power to the controller and a drain on your battery during storage. You can pull the fuse (in the panel under the driver's seat) or, as I chose to do, wire in a cutoff switch on the dash.


This worked perfectly to make connecting my brake controller to my 2015 Sprinter 3500 a plug and play operation.


I was concerned that I would not be able to feed this through with both connectors on but found a nice way to lay in the bundle



Still working great. Nomproblems


This product was supposed to eliminate any splicing of wires in my vehicle and the braking unit I purchased but does not. I will need to cut off one end and splice to the connector that came witht he braking unit. It maybe that this is not a standard connection but this cable was sold as a connection between the two. I do appreciate having the "pigtail" to the vehicles prewired connection.

This wiring harness is compatible with brake controllers from Tekonsha, Tow Ready, Reese or Draw-Tite. The brake controller end wont be compatible with other brands, but as you said, you can always cut the plug off and splice up the wires, color for color.


The customer service from order to delivery was excellent!!! I ordered a brake controller for our new RV but did not want to install it myself. Erica helped me find a qualified installer in my area. Much appreciated!


The adapter harness fit great, clipped right in at both ends. that said they 'cheaped ou't on the amount of wire in the harness, it fit but barely, life would have been so much easier if there was another 12" of wire.

The controller itself was just OK, nothing more. No on/off switch capability so it is always on if its in the harness. I wouldn't have purchased it had I known that, now it has to come in and out with each use so it doesn't bleed down the battery, what a P.I.T.A. Also the mounted bracket didn't really fit a Sprinter as suggested. I wish I would have purchased the DrawTight brake controller, lots easier fit into a sprinter junk tray.


This worked great once I found the plug that was buried under the drivers seat. This is the only way to go in my opinion

2020 Mercedes-Benz Sprinter

This made adding a brake controller to my sprinter van a lot easier. Unfortunately it’s not plug and play with the Redark controller, so I had to splice to the controller connections.


the controller and wiring harness made this almost the easiest addon I have done. Hardest part was removing the seat off the base on the Mercedes Sprinter chassis. Wow, that seat is heavy. But, the installation was soo simple and the instructions completely accurate.


Fit perfectly. Works as designed.

2020 Mercedes-Benz Sprinter 2500

As usual trailer fills my needs for my trailering stuff. They always have what I’m looking for and into my hands in a few days or less.


Easy ordering. They answer the phone too! Arrived on time.
Great experience. Thank you


The technical service after the sale keeps me coming back.


Used this harness adapter to connect to the factory brake controller harness provided under driver’s seat in factory tow-optioned Sprinter van. Worked as advertised and connected a Curt Spectrum brake controller to said factory harness.
