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?

plug IM1 (female) 6th gen plug that goes behind the glove box.
(pin) (where i wired it to) (what it does) pin1 = ecu plug E8 A- pin 21 = ACT function in the ecu pin2 = ecu plug E8A - pin 10 = AC1 funtion on the ecu pin3 = doesn not exist on 98 harness pin4 = st185 plug IH1 - pin 4 = this leads to the white/red wire on the AC pin4 = st185 plug IH1 - pin 5 = this leands to the white/blue on the AC pin 6 = II1 pin 3 = this is the tach signal from the ignitor PLUG 2c from the ST185 harness pin6 = EA1, fuse box plug- pin 10 = this comes from the black/white power line for the AC clutch that is on the AC compressor i THINK thats it. -------------------- 15PSI - 30MPG - Megasquirt Tuned
