Welcome to Allpar. If you don't already have them, I would try to find a factory service manual set for the car. Installing A/C in a non-A/C car is much more than wiring. Something like this:

The firewall is different between AC and non-AC cars. It will be some work to put factory AC on a non-AC car.
