I'm trying to iron out the bugs on my 3S-GTE swap, one of them I have not figured out yet is how to get the A/C pump to turn on. I've wired the US climate control unit in, and all but one of the wires (A Solid purple, I believe) had a direct match. Now, every knob and switch on my climate control unit functions properly except the A/C on/off switch. Can anyone direct me to a certain diagram and point out where it needs to connect or how to hook up the a/c pump? Thanks in advance.
