Did not know that, thanks for the explanation. There wasn't a wiring schamtic for the switch internals only a diagram to wire it up. Was trying to think of ehat the switch actually did going off the small window in diagram that tells the different pressures it switvhes at.

I thought the ground from pcm was sending a signal to trinary letting it know fan was running. Didnt think about the trinary telling the fan to come on.

Still have to connect all the wiring other than battery connections and what plugs into the under dash unit.

Hopefully I will have it fully installed over the next two weekends. Waiting on a new trans cooler and then its just wiring and cut/crimp compressor lines.

Then hope for a warner day to charge the refrigerant, or borrow a propane heater from someone to warm garage while I do it.
