Need help with some wiring
I have an electric fan and need to wire it so it will operate when the A/C is turned on, I'm not sure how to do it. The fan has a relay and the compressor has 1 wire going to it. Help please so I can use my A/C.

If you google "AC Fan Wiring" and look at the Images resulting, you'll see literally hundreds of ways to do it. This below is probably the most universal, but if you have a 2-sp fan I'd search for one specifically for that. This one also assumes a grounding temperature switch, and many do not do that (since they may be mounted in plastic radiator tanks).
A good tip is to go to the boneyard and snag the AC and fan relays. Good quality relays aren't cheap, and cheap relays are a PITA.
