The AC runs cold with the system configured when I bought it, and we just evacuated/refilled the system to insure we had the correct amount of R134a versus the factory-spec R12 fill.
Correct on the wiring.

The superheat im talking about is the temperature rise across the evaporator, you adjust the TVX for flow to put it in the optimal range for conditions, and to prevent slugging
