Can someone help? I have redone all the wiring with new harnesses. I would bet money that this brown switch wasn't hooked to anything when I took it out. I still have the old harness and can't see where it would connect. Anyway, it needs 12 volts to the pink wire for the fuel gauge to work. Before I rig something up, can someone tell me if this is supposed to connect and where?

Are you working with a wiring diagram?

I wish I had a good one. I think I found the problem though. I took the old harness and opened it up to find where everything is going. Problem turned out to be a dang fuse. I think that brown connector is for a different car or option that I don't have. Now I just hope that the gauge is accurate. It's pegged empty and there are a couple gallons of fuel in the tank. I guess I'll see when I fill it up.
