For you pac 2000 guys, where along the line did you tap A/C clutch switch? At the pressure switch? (trinary) Which side? At the A/C Blower switch? or somewhere in between?
Thanks in advance.

I have a Spal controller but it's on the trinary switch. If you don't put it on the trinary, it defeats the purpose of the switch. The trinary lets the fans run only when the condensor pressure requires more air flow, so they will not be running when going down the road unless the engine heat demands it.

The trinary switch usually has 2 blue and 2 black wires. The blue wires go to the fan controller and power. The black leads go between the evaporator thermostat switch and the compressor clutch.
