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?

so here is an update....

i added in the AC idle up system and it works great. all i did was tap into the black/white wire from the ac compressor, and ran that right to the AC vsv and from the vsv to ground. it ended up working very well.

That's a really good idea! Just make sure you turn off the A/C before you do any crazy full-throttle driving. You don't want to over-speed the compressor.

i dont think that would be a problem. the compressor has a speed sensor inside of it that tells the ac amp wants going on. the ac amp also gets a signal from the Tach so it knows what rpms you are at. so im sure there is some type of fail safe inside the ac amp that controls all that stuff.


i have to track down a mystery noise that im hearing. i hear something rattle around when the ac is on. when i put my clutch in, or turn the ac off, the noise goes away. at first i thought maybe my throw out bearing was making noised when the car idled too low, but now thats fixed and its still doing it. maybe the ac belt is too loose. ill have to go check it out.
