LT GRN supplied the B/U lamps - via the rear lighting harness.
Because of the presence of the grommet, it's likely that the transmission was changed from a 4 speed manual to either a 3 speed manual or an A/T. The B/U light switch used with a 4 speed MT is mounted on the transmission, while the other two types are located in the cab.

That would explain why I have no backup lights then.
The truck is an original auto trans. So, is the backup light switch located on the column?
Is it a part of the neutral safety switch?
Thanks for the help on this...
