If I remember correctly, it's gonna be either pin 41 or 42...can't remember if it's the blue or red connector though. If you search for "efans", I'm sure the info will pop up. The pcm has to be tuned to turn the fans on, so if you're having it done by someone (Nelson, W4M, PCMforLess, etc), you should ask them which pin they use, and if it's the red or blue connector). There are little numbers on the connectors if you look closely.

Hopefully someone who know's/remembers will chime in with more info.

Is Pin 42 on the Blue connector a +12v or a Ground "switch?

So if i were to wire my Efans up, i would put the wire that i now have goin to the mini switch there to activate the Relay?

in HP Tuners select "Aux. Fans", then go below that and set the Fan 1 temp settings how you like them, probably on ~210 and off ~192

the PCM gives a ground switch to the PCM pin for the fans, the A/C is a 12V+ trigger
