When ever I wire anything on a car I run a ground from the lamps I dont trust a body ground.. Rust or paint can interrupt the circuitBack in the early days of my working for the phone company I went on a panic call the al the lights on a switchboard were lite, it turned out that every light on a switchboard where lite. It turned out that the ground on the board was open and the lamps lite every one looking for a ground.
