Reverse lights not working!

[87Hi-v15HND]

So I have power to the rear harness plug for my running lights, turn signals and brake lights but nothing for reverse!

So I traced the wires all the way up to where they plug into the fire wall but from there I’m not sure where they go and what could be causing them not to work. Is it in the steering column? Need some leads here! Thanks!

If equipped with an AT, the switch is mounted on the steering column - down where it penetrates the firewall:

The DK BLU lead runs from the fuse block to the switch and the LT GRN runs from the switch to the B/U lights - in the rear harness.
