Have you looked in the FSM's Wiring Diagram Section? It fleshes out how the A/C is wired up in a stock car. The main thing is that with a standalone, you'll need to have the A/C Subharness, the one with FAC-01 and FAC-02.
How do you intend to do things regarding the A/C fan relays? All of my relays are integrated into a single fuse/relay box

I think what Akagis is getting at is to look at the Factory setup and then adapt it to your car.
Since the Engine is a bit different there may be a little tweaking that needs to be done and since it is a custom job there won't be any true answer readily available.
Especially in the NEW Member Tech Section.
You may want to expand your inquiries to the 3rd gen Section.Also ask in the Microtech ECU section on how to control the AC.

As I recall, the AC only ties to the ECU in one way: the A/C request line. I am unsure if the A/C compressor signal is controlled by the ECU or just informs the ECU that the A/C is on.
Regardless, the A/C is independent from the Microtech. Frankly the Microtech is too stupid to do anything with the A/C.
You'd just need to bypass the stock wiring through the ECU and connect the output of the logicon directly to the compressor (it goes through the trinary switch in series). Wiring diagrams are in the Haynes or FSM.
