I'm in the process too and keeping my ac on my 94, I talked it over with Jon and he added a trigger wire on my new harness for when I activate ac so that my idle will not be affected,, I'm not sure yet where to wire this in yet as I have yet to get the harness in and look things over, I'm hoping he may include an instruction where to wire in the trigger wire
I believe on a 99-02 ECU it will be pin 17 on the red connector, Dark Green with White tracer. No idea if it needs 12v+, 5v+, ground, or what. If I remember correctly this wire was connected originally to D3 on the C2 connector. Don't quote me on that though. The other possiblility is B5 on the C2 connector, this is a Lt Blu wire.
