Installation of Hayes Brake Controller Adapter

To install your Hayes 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, in which the wiring is run for you from the dash to the trailer connector on the back of your vehicle. Usually when this is done, a port is installed at your dash so that you can easily plug in a brake controller.

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.

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.

I ordered this for my 2017 Ram 1500. The package says it is for a 2010-2012 and 2015 Ram. I haven't tried to install it yet, but i am hoping there isn't a mistake. I can't rate this because of that. This review would not submit without a rating, so disregard the rating for now. 491912

Thanks for the review Jerry, our 2015 Ram 1500 is in the 4th generation Rams that are from 2009-current 2018 and the wiring adapters for the brake controller are be the same for this generation. I hope this helps and please let us know if you have additional questions.

Wiring harness could not be easier to install and use. Matched right up as advertised to existing wiring in my 2017 Ram 1500. 428323

No problems however for my 10 ft pop up there is a bit too much gain. At the minimum setting the trailers brakes in my opinion are a bit heavy
