Classic FAST and keeping A/C?

[peterkin]

I've seen tidbits of information from searches about having air conditioning with the FAST system, but nothing definitive. Could someone help me out and tell me what needs to be done for sure?

Classic does not adjust idle speed when A/C kicks on.

you need to ground the a/c clutch relay on pass fender, just splice the relay ground wireand run it to the blower ground or to a screw on the fender

but with classic when you run a/c it wont increase the idle rpm and it wont deactivate with wot
to have it deactivate at wot hook a low psi (5 psi or so) N/C hobbs switch into the wire for ground and connect to vac source , when you boost the a/c compressor clutch will disengage

With the xfi fast do you need to do any special stuff for the ac to engage ?

And you can adjust the cut off temp for the ac compressor if the coolant temp gets too hot the compressor wont kick on...

Thank you gentlemen, that's exactly what I needed. Not as complicated as I made it out to be thinking about how to do it.
