Installing 7-Way Trailer Connector on 2014 Nissan Frontier  

Question:

Helpful Expert Reply:

To install a 7-way, you'd first need to install the 4-pole flat connector (if you don't already have one.) I'd recommend the Curt wiring harness, part # C56225. Once that's in place, how you would proceed will depend on the trailer you're pulling.

If the trailer does NOT have brakes, but just the lighting circuits, you can simply use the # 37185 adapter. The adapter would plug into your existing 4-pole, and the white wire with the ring terminal on it would ground to the vehicle frame. The remaining blue, black and purple wires could be bundled up out of the way.

If the trailer does have electric brakes, and you want them to actuate, you'll need to install a brake controller using our Brake Controller Installation Kit, part # ETBC7. For a brake controller, I highly recommend you go with a proportional controller like the Prodigy P2, part # 90885. The P2 is one of our best sellers that's very highly rated by our customers mainly because of how easy it is to use. The Install Kit includes everything you'll need to install the brake controller, including the 37185 adapter mentioned above, as well as wire, hardware and circuit breakers. I'll link you to the instructions for the ETBC7 kit, as well as to an installation video showing the kit being installed on a Nissan full-size van. The vehicle might be different, but the procedure would be the same.
