Using the American autowire classic update kit and I'm down to the end and there doesn't seem to be a heater/ac harness. Is these correct? Was under the influence this was a complete car kit? Thanks

That would be a question you need to ask them. Looking at the installation pdf, shows wire #50A for the AC. Could not find the compressor side of the circuit.

The A/C harness is a separate plug in harness. The blower motor is still powered by the same brown wire as a heat only car, the compressor control wiring is part of the blower motor wiring harness. I think American Autowire offers the A/C harness if you need a new replacement.

You can reuse your old AC harness or purchase a new one from AAW; part# 16690.

I emailed them and they said the kit does not come with the ac harness on account of alot of people using after market ac systems. I guess I'll have to order one mine is pretty rough. Thanks

I installed this as well and was surprised the AC was not included. They said you can purchase it separately. I just left my old one in.

Did you have to replace your alternator? I got a 3 wire from Summit but there is a battery draw since it was originally a 1 wire? I'm trying to find an original 3 wire type alternator that won't draw power.
