Replacing Trailer Wiring For Boat Trailer


So im running new wires for my boat trailer.....question is for the running lights does it just run on one side or does it go all the way around


Expert Reply:

The running lights wire will run on both sides of the trailer and connect to any marker lights along the way to the Bargman Trailer Tail Light #30-92-001. I have linked a couple articles below for a 4-way and 7-way trailer wiring help guide.

The 25 Ft 4-Way Trailer Wiring Harness # A25W2GWB is a great harness to use for your boat trailer if it uses a 4-way connector. This harness is divided at the plug to run the proper wires down both sides of the trailer for the tail lights and marker lights on your trailer.
