Recommended Wiring For Third Brake Light On Camper Shell

Expert Reply:

Because trailer tail light systems combine the stop lamp and turn signals for each side onto a single circuit, you will need to use a vehicle-to-vehicle tail light converter, part # 118158 to split the brake light circuit back out.

The white wire on the input side of the converter would ground to the trailer frame, the green input wire would tap into the right turn circuit on the trailer and the yellow input wire would tap into the left turn circuit. The output side of the converter also has three wires. The yellow and green wires are not needed for this application, and could be cut short and should be capped off. The red wire would connect to your third stoplight, with the light also grounded to metal on the trailer frame.

Looking at the diagram I produced for you will give you a good idea of the wiring layout.
