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 beneath 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 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.


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.

2014 Jeep Grand Cherokee

I purchased this adapter cable to connect a used brake controller to my 2014 Jeep Grand Cherokee trailer wiring connector. It was a plug and play solution! The hardest part of the installation was fishing the adapter cable under the dash to avoid all the moving linkages such as brake pedal and emergency brake. What a great convenience!

  • How to Remove Brake Controller Wiring Harness from 2015 Jeep Grand Cherokee
    On the gray plug of the # HA81796-HBC that inserts into the connector, there is a locking tab that needs to be pressed in to unlock. I've highlighted that tab in the photo I've edited for you. Keep in mind, depending on how your 2018 Grand Cherokee left the factory, you might need to get the computer flashed at the dealer in order for the controller to work correctly once installed. I've linked you to an install video showing a brake controller being installed on a 2018 Grand Cherokee,

  • Brake Controller and Install for 2018 Chevy Colorado with Tow Package
    Your 2018 Chevy Colorado does have brake controller wiring to allow an install of one to be as simple as possible but it does not actually have a brake controller so you'd need one. Our Draw Tite iCommand part # 5535 is a really great option that's reliable, proportional, and priced great. The brake controller wiring on your truck is present under the dash which you'd wire the controller to. I attached an install video of a similar brake controller installed on a Colorado like yours.

  • How Does Brake Controller Install in 2018 Chevy Colorado
    Your 2018 Chevy Colorado has the brake controller wiring ran under the dash of the truck but there isn't an adapter that uses a connector. Reason being there's only 4 blunt cut wires under your vehicle dash for the brake controller wiring and not a connector of any type. To install the Hayes controller part # HA81760 you need the Hayes universal connector part # HA81789-HBC to run to those wires.

  • How Does a Hayes Brake Controller Wire to a 2011 Chevy Silverado
    On the 2011 Chevrolet Silverado Z71, the wiring for the brake controller is already ran and bundled underneath the dashboard on the driver side. This wiring may be taped together and tucked up and out of the way. There is not a plug-in wiring harness or brake controller port to plug into. In addition to connecting the brake control wires, there are 2 wires underneath the hood that will need to be connected (see FAQ and video).

  • Brake Controller Fit and Compatibility for a 2016 Jeep Grand Cherokee with Factory 7-Way
    Yes the Hayes Blackbird Brake Controller HA81726 will work for your 2016 Jeep Grand Cherokee, but you will need to use the adapter # HA81796-HBC to plug into your vehicles wiring. Can I offer one bit of advice? Instead of going with a Time Delayed Brake Controller I would instead suggest a Proportional Controller like the P2 # 90885 with adapter # 3045-P. The P2 is a proportional brake controller which means it senses how the tow vehicle is slowing or stopping and applies the trailer's...

  • Installing an Electric Trailer Brake Controller in a 2018 Chrysler Pacifica
    Since you already have a 7-way trailer connector and a brake controller all you should need is the adapter to connect the controller. That's assuming the 7-way is factory installed. If you've installed it yourself, or had it installed aftermarket let me know. If it's a factory 7-way there's going to be a connector under the dash above the steering column not far from where it goes through the firewall. The connector you're looking for probably has a green cover over it. Once you find...
