Hello everyone, I just replaced my front fenders on my 1953 3100 and the new headlight buckets have new wire harness I have 3 wires coming out of the bucket. can someone give me a wire diagrahm of the block that the wires go to there are three wires yellow, black and white. Does the black wire ground to the inner fender? The other wires were so old and covered with cloth I can't tell where they went. Can someone help? I have the terminal blocks with three screw positions
