In late cars, the AC Condenser fan runs all the time the AC is on. Connect
your fast idle solenoid to the wire which powers the condenser fan (
should be Blue/Black). Turn on the AC, blip the throttle once, and you should be
on fast idle.
On early cars, the wiring is more complicated because the AC condenser fan
only runs when the compressor cycles. IF your AC switch has an unused
terminal, check to see if the terminal is 12V when the AC is ON and the
compressor is OFF. If YES, wire that terminal to the fast idle solenoid. I have to
be a little vague about the early cars, because I don't know if the same AC
switch was used as was used in later cars.
Hope this helps.
Have fun today,

I have the exact same problem. I just installed a fast idle solenoid which
seems to work well but I have it wired so it cycles with the AC compressor
which makes it more of a pain than its worth. I thought connecting it to
the switch was the way to go, but turns out its also the deicing switch
which cycles the compressor. These solenoids need you to blip the throttle to
hold it at fast idle. they don't have enough strength to actually bump up
the throttle only to hold it. Maybe I'll put it on its own toggle that is
switched on procedurally for the AC and use it as a cold start adjunct as
well. Just a thought. Anyone have a solution so it will function the whole
time the AC system is activated? Is there a switched 12volt in the AC system
that stays that way even when the compressor is cycling
