14 dark green wire sends power to the compressor clutch. I don't know if I would call that a trigger, but it does turn the compressor on when the A/C is switched on. In the factory setup, the 14 dark green wire gets 12V when the key is on, the blower is not off, and the middle slider on the A/C control panel is all the way to the left.
