I have 68 that was a small block A/C car. It had a big block put in before I bought it. I removed what was left of the A/C case and the wires that existed for the AC are a mess. I am not putting any fan or heating system back in. My question has to do with the wires that go to the fan/AC relay. What do you do with those wires including the one that goes to the horn relay? Just omit it?
