S14 A/C Wiring Dilemna

[Ramius83]

Ok guys. I completed my brother's S14 SR20 swap about two weeks ago. I did the wiring myself, everything works perfectly fine. All wiper functions, consult plug, etc work fine. However, the A/C wiring has been giving me some fun.

On the SR F4 plug, there are 3 wires dealing with A/C. Now, the KA M63 harness has about 4 wires dealing with A/C. The SR20 F4 plug has three wires marked: A/C, A/C Relay, and Thermosistor Control Amplifier (A/C Switch). The KA M63 harness has four wires marked: Triple Pressure Switch, A/C Switch, A/C Relay, and A/C Hand Switch.

Now, I don't want to just start hooking up wires and possibly fry something. Who has done the wiring on their setup and has a fully functional A/C system that properly kicks on and off as needed? And what wires do you wire up?

And please don't say "search" as I have already done this quite extensively. And I am no idiot to swaps as I have already done this plenty of times, just not with a swap that the person wants A/C, whom of which is my brother in this case. Thanks everyone.....
