ok... so my AC hasnt worked since the swap and i figure now is a good time to wire that crap up. so i have my harness apart and im trying to look at the wiring diagrams to figure out a few things. seems like i need some help.
"ac amplifier" in the diagrams means the main AC compressor, correct? on it, is a plug called A8 (looking at the 5sfe diagrams). the harness goes from there to a plug called IM1 and then 3 wires go to the ECU's 1st plug. where is IM1 located ? is it the white, 5 wire plug that goes from the 3s hanress, and plugs in right behind the glove box?

Like I said use the IDL signal from the TPS to trigger a relay that is powered by the AC magnetic clutch signal. That way the VSV will only come on under two conditions, 1. you're at idle and 2. your compressor clutch is engaged.
