Question:
how do you ground a tow bar from the pickup to the trailer?
asked by: Dave
Expert Reply:
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.
