The Air Conditioning (AC A/C):
The symptoms: The AC light turns on on the dash, but doesn't do anything -- the AC magnetic clutch isn't engaging.
The solutions: Aparently the Gen3 runs the AC in a similar manner to the NA as it uses a pink/green wire in IE3 to trigger the AC amplifier as to when it's supposed to turn on the AC compressor. We found this wire present, and the car seemed to be wired on the kick panel for this wire also, but the gen2 harness we removed didn't have this wire. So we cut this wire. We also found that there was supposed to be a tach signal from the ignitor going to the AC amplifier on IE4 pin 10. This was also an empty pin on the wiring harness for the Gen 3 -- so we inserted another pin, and wired it to splice in to the IE1 connector's tach signal to the dash.
The other wires missing on the gen 3 harness appear to be the idle up wiring for the idle up VSV -- but I believe as long as the gen3 ecu is getting the signal that the AC is on (black/white wire) it is controlling the idle up VSV as that appeared to be what was happening.
I hope this helps some people out there with 3rd Gen swaps.

I had to 205 compressor on the car, but I took it off because I figured it was not compatible.
The magnetic clutch will not engage on the compressor.
Everything in the AC system is 185 except the AC idle up valve.
• I was looking at the ECU wiring and the 205 ecu controls the AC idle up valve, and the 185 does not.
So what controls the 185 AC idle valve?
• The 185 ECU has a control for the magnet clutch, but the 205 ecu does not. In its place is a second A/C amplifier.
I have included the AC portion of the ECU guide.
This copy is of the 205 bgb, in red is the 185 components.
Any insight is appreciated.
