Which of the 3 wires for AC Pressure Sens.

That third terminal on the switch you have is a ground, basically you have an on-off switch and you need a 2 way instead. No ground on the 2 way, middle terminal is the destination and the terminals on each side are the channels.
So, switch to 1 means the PCM reads AC sensor, switch to 2 means PCM reads WB.
