Custom Wiring Adapter for Hayes Brake Controllers - Dual Plug
part number: HA81794-HBC

Install your Hayes electric trailer brake controller quickly and easily with this custom wiring adapter. One end plugs into the controller, and the other plugs into the built-in port behind your vehicle's dash.

Features:

  • Plug-in wiring adapter allows for quick, simple installation of your electric trailer brake controller
  • No cutting or splicing required
    • Custom connector end plugs into the built-in port behind the dash of your vehicle
    • Opposite end plugs into the back of your electric brake controller
  • Compatible with time-delayed and proportional brake controllers from Hayes
  • Made in the USA


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 built-in connector behind your vehicle's dashboard. To access this connector, first locate the instrument cluster finish panel in the center of the dash, near the driver's side. Carefully pry the panel out and undo the locking tabs to remove the panel. Plug the adapter into the mating connector in the large gray housing behind the panel.


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.

Etrailer was very helpful with all the info needed to buy the correct connecting cable for my Hayes brake control. Delivery was quicker than expected & of course the cable works as stated. Great job again! Thanks Etrailer! 734677

This harnress was exactly what I ordered. Very pleased as usual. I have to add that for a while I was sure that I had received the wrong product. Then I watched an Etrailer install video and realized that the plug in my truck had an adapter attached that had to be removed before the harness could be plugged in. 5 minutes later I was done and ready to tow. 528384

I, order wrong wire adapter by mistake, I called etrailer, and spoke to nice lady there and gave the number of the one I had ordered, she looked up what I needed and placed order while I was on the phone with her. Got the adapter and it was the correct one and works perfect. To help others Ford puts a hard shell in there wire to protect against short circuit, it has to be removed before you can plug any adapters into it. 420629
