I need to set up my E8 to Idle-up when the A/C comp kicks in. The ecu is already connected to the IAC, I suppose I also need to hook up some sort of input for it to know when the compresssor is on. In the spare a/d optons, I see a/c request , Is this it? It also asks for a 5V signal. Where do I find this on the A/C system?

Any help will be welcomed.
