Yeah that’s where I’m stumped too, DD says its looking for the 12VDC source that the clutch gets to trigger it. So the only way I can get it to make sense in my head is to wire it like most of the genetic diagrams show. One to common ground, one to ground side of fan relay, one to the compressor, and then just jump the last wire from the trinary to the 12VDC clutch trigger and from there to the fan controller. I really appreciate you taking the time to look into this for me also.
