my cruise stooped working in my 95 tahoe. Found out the turn signal switch went bad. Auto part stores want 200 bucks for it. I got lucky at the junkyard and found one in a 95 s-10 blazer for 5 bucks. Has normal wear but works like new.
The write up has a little to much thought into it. If you trace the wiring down it goes right by the engine fuse box. You can get power from there and hide the relay inside the box and use a lot less wire b/c the headlight wiring harness goes right by the fuse box.
