The trailer itself will have a ground wire from the trailer connector that needs to be attached to a clean and corrosion free bare metal surface on the trailer frame. The lights like in Incandescent Trailer Tail Light Kit, # TL5RK, will ground through the mounting studs. The truck side trailer connector will also be grounded to the vehicle frame. The trailer itself will ground through the coupler and trailer ball.
