I can, but it won't have GM PCM control over the compressor.  It will have PCM control over the fans (turn the fans on when you turn the AC on) and PCM control over the idle (PCM will raise the idle accordingly to compensate for the additional load of the compressor).  You can get some compressor protection by including an RPM window into your relay control.  I can supply one and make it up as part of the harness if you like.  Window switchs range from $50-150, depending on how snazzy you want it.

Greg,

Will this work as the compressor switch protection you are talking about. It's inexpensive and looks "snazzy".  :)

If you've got an ls2, yes that will work fine. If you've got an ls1, it is not needed.

Are you still doing these harnesses?  I am getting weak and considering putting A/C in my FC.  Will this allow the A/C button on the logicon to turn the a/c on and off and the PCM to control it?

Yes, you'll need to connect one wire to the AC Request circuit at the old Mazda ECM connection, a wire to key on power, wire to ground, then plug into the compressor and GM AC pressure sensor.  Once you're lines are made, everything will work like stock.

Ac lines are on hold right now. My distributor has gone a different route and no longer offers ac parts. Looking for another now.
