Oh ok cool, did you do a 2gr swap? Yeah I thought of doing that but I'm not sure if the AC would work if the 2zz ECU if it isn't connected/engine running (like as in if it requires an RPM signal to allow it to kick on)...I could be wrong though.
That and the engine idle signal to the 2zz wouldn't do anything...
2zz ECU still connected to the body side harness
2zz ECU wired directly to the 2gr AC comp.
AC signal going to 2gr ECU for idle increase (this Id have to figure out)
Figure out how to trigger radiator fans from 2gr ecu...
2gr ECU and AC comp,
AC Clutch wired to lotus AC on button 12v
AC compressor solenoid/pressure switch wired to either the same 12v, (that or the more complicated way; wired to some kind of temperature control switch to switch the valve on and off according to temp)
Aftermarket Fan controller with AC override input
The first one would be better because it wouldn't involve going into the front and rewiring fans, and also would still compensate for speed, but the second one is much simpler... man who would've known AC and radiator fans would be such a pita
