P28 Fan Control w/ A/C

Post by EGAJohn »

I have a 98 Integra with a P28 S300v3. I'm using a Rywire tucked harness with chassis adapter and just finished wiring the A/C system from scratch. My last concern was the fan control. I currently have the A12 FANC pin triggering a relay for the radiator fans which has been working great. I was wondering if that same output will trigger when the A/C switch and A/C clutch are active. If not I was thinking of either running a diode to have two trigger sources from A12 and A15 or just running two relays with the A/C relay overriding the FANC when the air conditioning is on. This is the last thing I need to figure out before I get it charged up. I just confirmed my A/C switch input is working and my A/C clutch relay is working properly when using the test output function.
