How to make AC work with your swap, aka: Need help with AC wiring thread Options

[lagos]

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?

i thought of another simple way of doing this. the basic problem is that with the AC on, the car idles too low. so you can also add the idle up in, simply by taping into any wire that gets 12v when the AC BUTTON (not clutch) is pressed. a good place for this would be to tap the purple wire that goes to the presure switch. this will make the car idle at something like 900 rpm, instead of the normal 800, and when the ac clutch comes on, it will only dip down to 850rpm and not the 700ish that makes the car idle crappy.

this way, you wont have any issues if the system making the rpm's jump up on their own while you are driving, and you wont have to mess with the TPS singal or use a relay.
