The switch is inside the cab, on the steering column just before it hits the firewall. Haven't done it but the procedure is something like this:
1. Connect lead to back-up light switch.
2. Aline actuator on back-up light switch with hole in shift tube.
3. Position back-up light switch on cutout in lower part of steering column jacket.
4. Push down on front of back-up light switch. Snap 2 tangs on back-up light switch into
place on steering column jacket.
5. Adjust back-up light switch by moving transmission gearshift lever to “P“ (Park). Main
back-up light switch housing and back-up light switch housing back should make a clicking
noise, providing proper adjustment.
I was about to follow these procedures but when I finally found the switch, it was un hooked and the wire was taped up. Hooked it up and it worked. I guess some people don't like lights.....
FYI it is from the TM 9-2320-289-20 manual page 4-41
