School me on A/C operation and wiring. I finished deleting all the unnecessary items. I unpinned the A/c stuff, but I do want AC. So i need to go pin all that back in?
I guess I'm confused on how the pcm and AC cab controls communicate.

I would keep it all separate. The engine will stable itself when the compressor turns on and you can run a relay to have the fans turn on when the compressor turns on.
I'm going to use a mechanical fan.
So just hook the compressor and such up to the original wiring? That's what I was hoping

I know that if you leave the AC in the harness and tune then there is a lead in the harness that when you ground it it will activate the compressor clutch. I'm not sure if That lead would need to be hooked up to a binary switch of your AC system or if you run that to your switch in the cab and inturupt the compressor with the binary switch. Honestly I have no idea
Got this from alldata if it makes sense to anyone.
Brendan from lt1swap got back to me.
There are 3 wires needed, AC request (12v+ to pcm) low cycle switch, and a ground. The computer will command a relay with a ground control for a/c clutch relay.
