Re: reverse light switch
I have a 91' with about 107K on it, and my reverse switch developed a short about 6 months ago (I haven't corrected it yet) My problem was that it shared a fuse with something more important (the turn signals if I remember correctly). I disconnected the switch at it's connection under the hood. I think I remember it being in the middle of the firewall up high.
I'll take the thing out when I replace the engine and see If I can make it work, or break-down and do the dealer thing.
good luck, and I'll keep watching the thread
