Backup Switch Wiring

Murray: Thanks a lot for the information, once again that's what I needed and it's greatly appreciated. I had most of it figured out except for where you stated that
"one of the violet wires changes to white and goes up to the radio connecter where it splices into the red wire." I'll find that connection and then should be good to go.
My 68 fastback`s orig type tail lenses are in pretty good shape, but the back up lights aren`t bright enough to worry about. I had a switched wire laying in the trunk from a total rewire and hooked it up to mt b/u plights, just the he-- of it, "not worth the effort !"
