Hi,
When I got my Chevy c10 it had some different lights added on the back with a flat bed. I now baught the full bed, put it on, I have been trying to get the wiring worked out. I saw on my friends truck (he has a 65 c10 also) that there are three wires running back. I am wondering are there two grounds and one power or two power and one ground. I am thinking possibly there are two power and one ground that goes from the left side light to the right side light. Any help would be great, a pic would be great also. thanks.
