I should have been clearer in my post. I'm using the VA trinary switch. So I have a wire from the compressor to the trinary switch, a ground, a wire from the trinary switch that ties into Fan 1 which is controlled by the ECM, and the wire in question is from the trinary switch to the AC Thermostat as stated in the PRC radiator instructions. The only wire left in the VA harness is the blue wire so I assume that's the feed to/from the ac thermostat?????
The "key on" ignition source for my electric fans is also supposed to tie into the ac thermostat switch as well. It's probably staring me in the face but I see nothing in the VA instructions about this ac switch.
