Kswapped Insight, A/C is working but ECU is bypassed. Searching high and low trying to figure out how to wire in ECU but all I can find is vehicle specific questions that don’t explain exactly how it works. Can anyone post a generic diagram link? I feel like the advice I’m getting will let the ECU know when ac is on but not how it controls the compressor or even if it does.

Use VTP as the A/C input. The ECU does control the AC clutch via E18 - use the RSX manual to see the wiring.
