Installing Brake Controller in 2014 Nissan Pathfinder Without Install Port Under Dash


I purchased the Hayes genesis #81790 and Hayes wiring harness #081786-hbc for my 2014 Nissan sl pathfinder. Vehicle does not have a towing package but the port to plug in the controller is somewhere under the dash although I am unable to find it. I am beginning to wonder if I purchased the correct item. The trailer hitch and all wiring is installed and works. Will this work or do I need to look at this again? Thanks.

Since your Pathfinder is missing the brake controller install port under the dash you are going to have to hardwire in the brake controller # HA81790.

For a wiring kit to install the brake controller to the 7-way you would want the Wiring Kit for 2 and 4 Brake Electric Brake Controllers # 5506. This will provide the power source and ground for the wiring for the brake controller. You will need to test the wires from the brake pedal switch of your vehicle to find a circuit that has voltage when the brakes are applied and none when not applied. This will be the circuit you will run the red wire to.

Finally you will need to run a length of 10 gauge wire (part # 10-1-1) from the brake output circuit of the controller to the brake output circuit of the 7-way (blue wire). The # 10-1-1 is sold by the foot so you will need to order a quantity of the amount of feet you will need.

I attached an FAQ on installing brake controllers for you to check out.
