Is there a fuse specifically for the reverse lights on 93 Sierra
 

I looked but none are labeled Rev or Reverse Lights.

I also searched but didn't find it.

Yea I assumed that was it but I thought I was wrong.

That fuse is good and my blinkers work fine but I have no back up lights.

I checked the bulbs too and they are good.

Jump the wires at the switch and see if the lights come on.

It should be a dark blue wire and a light green wire.

Neutral safety switch needs to be adjusted? That selects the back up to turn on.

I had given up on this but now I'm back on it.

The little cable that goes to the shift indicator is broken or came undone.

Does that have anything to do with the reverse lights?

No...... That shift indicator wire is spring-loaded, & only attached by a 'clip' on an edge.....that moves as you select a gear shift... You may be able to see from wear, where it was attached.

Difficult to describe here, but I think, if you remove your plastic gauge frame, and maybe the lower dash trim (?), ..you can get to the indicator wire, and re-attach it. Once you get in there, you may see how simple it works. Put a little Vaseline to lube the sliding indicator pin.
