Can anyone tell me what pin on a 2002 121 pin ecu (ALH) gets the "AC Switch" signal? I see on VCDS this one will actually raise the idle and I assume might do somthing to the timing and fuel maps.
I found the "Compressor ON" pin that does not raise idle or do anything that I can see but in the bently I dont see the "AC switch on" pin.
