No back up lights
Yes, the neutral safety switch is on the auto tranny and working, the wires are plugged in, and it isn't the bulbs. The truck was a basket case when I bought it. It's a 79 F150 that has had the motor replaced (460 to 400, already there when I bought it, but not running).
One of the problems was the nuetral safety switch, truck started in all gears. We determined that the switch was good, but there was a problem somewhere in the wiring. The solution was to cut the bad wire (red with blue stripe) between the ignition switch and the selenoid and splice in a new section. I'm guessing that the backup lights hook in somewhere in that bad section we bypassed.
Any suggestions, short of buying a new harness? Tearing into the harness to chase down the connection isn't feasible either since my back is no longer up to all the bending and squatting needed (it's hell to get older).

Was the truck originally a manual tranny? You never know, the cab may have been replaced at one time too. That would explain the missing wiring for the neutral safety switch, and also the back-up lights. You will probably have to follow the same program as you did with the neutral safety switch:
Find a fused hot wire.
Feed the switch on the side of the tranny with it.
Find the original back-up light wire in the harness and hook it to the output of the tranny switch.
Make sure your tranny switch has four wires. Two for the neutral safety switch and two for the back-up lights.
