Parts Needed to Install a Hayes Electric Trailer Brake Controller on a 2005 Nissan Pathfinder

Expert Reply:

There are a couple of different ways you can install a brake controller in your 2005 Nissan Pathfinder. If the Pathfinder came with a factory installed 7-Way trailer connector, you can use wiring harness # 20266. One end plugs into a port on the vehicle and the other end with bare wires attaches to the wires on the brake controller # 81741B color for color.

The port on the vehicle will be located underneath and left of the steering column, taped to another harness near the emergency brake pedal. I have included a link to the installation instructions for you.

If the Pathfinder did not come with trailer wiring, you will first need to install Tow Ready Custom Fit Vehicle Wiring, # 118263. I have included a link to the installation details and a video for the wiring harness.

With the 4-Way installed, you can then install the 4 and 7 Way Installation Kit, # ETBC7 which will add a 7-Way in the back and provide the wiring for a brake controller. You will also need a circuit tester, # 3808, for brake controller installation.

I have included a link to an FAQ article and a link to a video that explains how to install the ETBC7 and hardwire the brake controller.
