  • Vehicle Specific

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 junction box beneath your '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 electric junction box beneath 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.


Junction BoxBrake-Control Adapter Port

This adapter plugs into the port that is built into the electric junction box underneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.


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.

Video Transcript for Hayes Brake Controller HA81781-HBC Review

Today, we'll be reviewing part number HA81781-HBC. This is the Hayes custom wiring adapter for the Hayes brake controllers. It is a dual plug set up. This is going to fit Chevrolet models Avalanche 2002, Silverado 1999-2002, Suburban 2000-2002, and Tahoe 200-2002. It's also going to fit GMC Sierra 1999-2002, Yukon XL and Yukon with amber turn signals from 2000-2002, and the Yukon XL Denali, and the Yukon Denali with amber turn signals from 2001-2002. This is also going to fit the Cadillac Escalade in year 2002. This does require that your vehicle has a factory tow package wiring.

No cutting or splicing of wires is needed. The custom connector plugs into the electric junction box beneath the dash of your vehicle, and the opposite end is going to plug into the back of your electric brake controller. Today, I have a brake box, and I just want to show how easily these 2 systems connect. Just like that, it's connected, and you're ready to get on your way as long as you have your factory wiring connection made. To disconnect, you push down on the tab and pull the 2 halves apart. This wiring is going to be compatible with the time delayed and proportional brake controllers from Hayes. The distance that we have between the 2 ports is going to give us 2' in length. That's going to do it for today's review of part number HA81781-HBC. This is the Hayes custom wiring adapter for the Hayes brake controllers.

I was needing to install a brake controller in a newly-acquired 2001 GM pickup. The truck already had an available plug-in port, and I was looking for a connection cable between it and the controller. Due to their strong reputation for good business, I checked with eTrailer first. They not only had exactly what I needed, but the price was about the lowest around. I ordered the cable, and the shipping was fast. As expected, the cable fit perfectly, and was the precise length necessary. I have used this company before this order, and rest assured, I will do it again. 664464
