Reverse lights
Fellas,
Can someone give me a wiring diagram as to the rear lighting. My reverse lights dont come on. Looking at the thread with the favorite mod of bright reverse lights i think i might do that as well while i am under there. But for now i would like to get them working. Everything else works, just not the reverse lights. Thanks!

Can`t help with a diagram but what you should have is a combined neutral safety switch and rev light switch mounted on the outside of the C6. With the running lights on you should have 12v at one of the wires at that switch. Then with the shifter in Reverse you should have 12v going out of the switch to the rev lights.
That`s as I understand it (hate electrics).
If you have 12v to the switch but not out the switch may be bad.

Doesn't matter if the running lights are on or not, the reverse lights are on if you shift into reverse. I know on a couple of mine the switch needs some adjusting, you have to wiggle the shifter a bit to get them turned on sometimes.

Doesn't seem want me to add the picture to the thread for some reason but there is a picture for your trucks (1989 Ford Truck F 350 4WD Pickup V8-7.3L DSL) back-up light diagram at the following link (in my album):

Hope that helps!

So what would be the best way to determine if the nss is bad? Can i just poke through the wires and see if i get power when it is in reverse? Any idea on the color of the wire that goes to the reverse lights from the nss? I know the colors are good so no franken truck issues there! lol

Should have key on 12V at the Purple/Orange wire
12V through switch when in reverse at the Black/Pink which feeds the back up lights.

There are quick connects close to the NSS. First isolate which wires are for the NSS and which are for the reverse lights - 2 for each.
Then you can do a simple continuity test between the exposed connection tabs to see if the switch is working. Probing the wires will also work but considering the amount of sand and salt those wires get exposed to in the winter, I would avoid doing that.
