Anyone know how to tie the 05 fans with the manual switching wire (its green on a PCM4less harness) into the factory AC system wiring so it will turn the 1 fan on regardless of engine temps? I'm sick of sitting in traffic at 1700 when its 88degrees and 88% humidity and my ac blows hot coffee on me until I get rolling again.....

 

theres a wire in PCM Clip2 that has the A/C clutch signal, don't know if that would work, I can check what pin it is when I get home if that helps

 

There's a big loom of wires that runs past the alternator bracket just to the right of it, the green wire in there goes +12V when you turn the a/c on. That's the wire that the Nelson harness taps into for the a/c signal. You can see it in the linked pic, there's a T-splice connector attached to a green wire that sticks out of the loom. The Nelson harness works the way you describe, turns one fan on high any time the a/c is on and the turn-on temp is not reached, turns both fans on hgih when turn-on temp is reached and the a/c is on. Keeps the a/c cold regardless.

 

I believe that on the PCMforLess harness you need a ground to the manual turn on wire, unlike the Nelson harness which uses the 12v+ signal from the compressor.
