*BUMP*
Im *guessing/thinking* - for wiring/pcm etc I need to .....
1) Enable FAN#1 if not enabled. Disable FAN#2 so only 1 fan.
2) Blue connector #41 -> add a pin to go to fan relay to ground circuit.
-- This will give you electric fan control based on engine temp.
-- But now for AC
3) Add trinary switch to compressor circuit to switch on/off fan based on hi/low pressure signal.
a) Not quite sure if thats right
b) The wiring exactly
