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.

For most applications, the factory plug is located beneath the dash, near the center console.

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.

Ford F-250 Super Duty

Once my son-in-law tracked down a burned out fuse and we eliminated the previous owner's wiring mess at the back bumper, the new brake controller and adaptive wiring turned out to be "plug and play" on my '96 F250. Worked just as easily as the wiring harness from etrailer that got me trailer brake lights from my '94 Jeep XJ several months ago. If I need something else for trailers, I'll check etrailer again. 450765

2017 Ford Explorer

I have a 2017 Ford Explorer Sport with the 5000lb tow package and there was contradictory information about the factory installed grey brake controller connector being there. I ordered the Hayes Brake Controller and the wiring harness and took a chance. I had taken a look before ordering but couldn’t see it. Once the parts came I went ahead took off the plastic panel under the steering wheel and the metal plate underneath it. Tucked high underneath steering wheel the grey plug is there. Plugged in the wiring harness replaced the metal plate, attached the Brake Controller bracket to one of the screws that holds the plastic panel. Done. It took less than 30 minutes. I haven’t hooked up a trailer yet, so I have no comment on the actual usage of the Brake Controller. But if anyone has a question about the grey plug for the factory installed brake control wire on a 2017 Ford Explorer Sport, it’s there. 633545

I needed a brake controller for my vehicle that I am going to use for towing a new travel trailer I purchased. I found the etrailer site on the internet and was able to quickly locate an appropriate controller and vehicle specific connection cable. My order arrived in a timely manner. All of the necessary installation information was included and I was able to install it in my vehicle in just 20 minutes. Very pleased with the whole process. 451028
