IDK how the circuit is currently wired/routed - but some modifications must have been done. As original:

The cut leads went to the switch for the backup lights.

DK BLU is/was hot from the fuse block (fed by the 15A TURN B/U fuse)

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.
