I unplugged it at the tranny and had power there so I took the switch out and tested it, it was toast. So I got the heat gun out and melted out the plastic to get it apart and then figured out how it worked in there. And rebuilt it with part of a wire connector,a washer and a small body plug and my old stand by crazy glue and baking soda.Put it back in now I have backup lights!!
Thanks!
