Install your electric brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in harness beneath your vehicle's dash.
Features:
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.
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.

Install your electric brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in harness beneath your vehicle's dash.My car came with a tow package but without trailer brake control and so it had a plug to connect the controller to. This plugged into that and voila. I had a place to connect the trailer brake controller. I know little to nothing about cars and was able to do it myself. 10/10 would recommend. Saved me a custom job bill.
its the simple way to add the brake controller. Just plug and play. No splicing and discing of the of the vehicle wiring harness.
Easy ordering, fit perfectly on my 2021 Jeep Grand Cherokee... So much valuable info on etrailer, and very reasonable shipping to Canada !
Jeep is not making brake controllers or wiring adapters for my vehicle. Glad my RV dealer pointed me to check with Tekonsha and etrailer.
This wiring adapter will make the installation of the brake controller much easier and more reliable than splicing wires. Look on YouTube for an installation video.
Great product. Easy fit. Makes installation real easy

This is a great product, easy to use. The adapter specifically for my vehicle made it all easy to use and easy to install. Highly recommended. The dual trailer option is very handy.
I ordered a wiring harness for a trailer brake controller and paid for quicker delivery. I received a clear lens cover for an interior dome light. Customer Service did answer the phone and said they would try to send the right part… but the parts delay makes a trip with the trailer impossible.
I recently purchased a new Jeep Grand Cherokee L with the trailer tow package. I was looking for a replacement adapter for my Tekonsha Primus IQ. This particular wiring adapter was not a guarantee fit, but after plugging it in to the harness on my new vehicle it works fine. So, based on my experience, this adapter does properly work with the tow package wiring on 2023 JGCLs.
Perfect fit for my 2024 Jeep Grand Cherokee. Super quick install.
Plug and play with proper wiring harness made installation a snap. Break controller worked great on our Jeep Grand Cherokee. I highly recommend.
Make sure you get the plug in wire adapter but it was already part of the purchase
Worked perfectly with our Jeep.
Wirks perfect for my durango
Plug and play as advertised. The wires are nicely protected. I mounted my brake controller under the dash, just below the ignition. I had plenty of wire.
Perfect fit for my grand cherokee.
Great experience, easy installation. Shipping to canada right now was a 3 week ordeal but overall that is the only drawback. Yes, I would buy from etrailer again.
Great service towards parts being processed and sent out in a timely manner.
Besides receiving my product damaged, and three days late, I am unclear as to why the individual who packaged my product didn’t replace the box. I hope you have a wonderful Christmas and a happy new year.
Reliable, works as advertised.
Works great, fast delivery!
