Replacement 4-Way Flat Trailer Wiring Harness For 10' Trailer


have a older10 foot trailer that has bad wiring. which kit would be the best one to rewire it?


Expert Reply:

This will depend on your trailer and how you prefer to wire the lighting.

For a steel trailer you can use a 20 Ft 4-Way Trailer Wiring Harness # A20WB. This harness only has a 30" ground that will attach to the trailer frame and all the lights will ground to the trailer frame to complete the circuit.

The 25 Ft 4-Way Trailer Wiring Harness # A25W2GWB has a ground wire that runs the full length of the frame. With this harness you will not use the frame as a ground circuit so all marker lights and tail lights will need to be tied into the harness directly for the power and ground wires.
