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?

well the Black-White wire from A4 goes to a splice point. one end goes to grey connector E7 pin 10. the other end goes up to another splice point. one goes to A/C magnetic clutch relay pin 1. and then other end goes to A/C condenser fan relay NO.3 pin 2. Those are both located in the relay box 5.

the Yellow-Black wire from connector A4 goes to a connector called IH1, pin 3, from there it goes to A/C amplifier connector A17 pin 5.

the White-Blue wire goes to the connector IH1 pin 5, from there, it goes to connector A17 pin 9.

The White-Red wire goes to IH1 pin 4. then to a splice point. one end goes to A17 pin 14. The other end goes to A26 pin 1. this is a 4 pin connector. A/C Thermistor

Pin 2 of A26 goes to A17 pin 16 and is a Yellow-Green wire.

Pin 3 of A26 is a yellow wire, and goes to connector IJ1 pin 5. from there it goes to a splice point. It then splits off and both end connect to other splice points.

I will describe one first..

one side leads to another splice point and then goes to A/C room temp sensor A23 pin 2. then A23 pin 1 is a White-Red wire and goes to connector IQ1 pin 7, then goes to AUTO A/C AMPLIFIER A34, pin 5. the other splice goes to connector EA1 pin 5, which then leads to A/C ambient air temp sensor A1, pin 1. then Pin 2 of A1 is a Yellow-black wire. it goes to connector EA1 pin 4, and then to connector IQ1 pin 1, and from there goes to AUTO A/C AMPLIFIER A34 pin 6.

OK now here is the second one....

Goes to connector IQ1 pin 2, and then goes to splice point I11 where it goes 3 ways. One way is a purple-white wire, that goes to A34 pin 15. Another purple-white wire goes to connector IQ4 pin 14, from there goes to A/C control assembly connector A18 pin 7. (this is a 25 pin connector)

The splice point I11 also has another yellow wire that lead to another splice. The yellow wire then goes to AIR MIX CONTROL SERVO MOTOR, A29 pin 3. (this is a 6 pin connector.) the other wire coming from this splice point is a Orange-black wire. This goes to the A/C water temp sensor A27 pin 3 (this is 4 pin connector). Then pin 1 is a Red-Green wire that goes to connector A34 pin 20 (Auto A/C Amplifier)

and thats it i think.. unless you want to know how the Air Mix Control Servo Motor A29 is hooked up.
