How do I setup my AC System in the tune?
Here is my file.
My vehicle is a 98 Silverado with stock 98 AC system.
My AC light wont come on and I checked all my wires at the PCM and they are in the correct locations.

Im mobile so look at your tune. But what wire harness did you use? Sounds more like a wire issue than tune. Helped with a swap like yours and all went well. Purchased wire harness though.
I used the original wires and pinned them to the new PCM. I checked it over tonight and I am not getting a AC Request Signal from the Climate Control Module. I tested the wire coming from the switch and I have no change on the wire whatsoever. Right now I have it rigged with a switch to turn on a fan and send the signal to the AC relay. Temp for now til lI can figure out what is going on.
