Recommendation On Installing A 7 Pin Plug


So I bought a trailer that came with a 7pin plug but it only comes with 3 wires red black and white how do I even connect them to the lights

When it comes to your trailer that has a 7 pin plug but it only has 3 wires (Red, Black, and White) I recommend starting all over using The Bargman 7-Pole, RV-Style Connector - Trailer End - 22 foot Long # 50-67-008.This molded 7-way, RV-style, trailer-end connector with a 22 foot long cable lets you replace a damaged wiring harness on your trailer.

The wire configuration is as follows:

Yellow: center auxiliary
Green: tail and license lights
Brown: right turn and stop lights
Blue: electric brake
Black: battery charge
Red: left turn and stop lights
White: ground wire

The black/white wire is a 10 gauge wire, the blue wire is a 12 gauge wire and the brown/red/green/yellow is a 14 gauge wire.

I have attached an review video below.
