I'm trying to get power to my a/c compressor after s52 install in 88' 325is. I've got power at c103 off a/c button . Orginally signal/power went to ecu with m20,right? Now I need power to compressor, my aux fan works with a/c button when pressed ,It as simple as pulling compressor power off aux fan power or would it be better to contuine power off c103 to power up compressor?? What are you guys doing for this?? thanks , joe
