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?

yeah... i think this is whats going on.

i traced the power routing for the whole ac system. it goes right from the AC fuse, to that presure switch on the AC lines. then the power goes to the AC amp. the sensor also has 2 more lines that are tied into the Fan relays. if i unplug the sensor, the fans go into their fail safe operation and stay on all times.

also, when i press the AC button ON, the sensor gets power to the wire that it should. so i think everything is wired up right. i think the wiring is right, i just need to get it recharged. i can also jump the 2 wires in that sensor and see if my AC clutch kicks in, to test things out even more if i want, but i dont know how safe it is to engage the AC clutch without any gas in there....
