I use one of these. It is a killer set-up. I just assumed the OP was trying to use some type of factory set-up instead of an aftermarket deal.

I have mine controlling dual 16" fans. I think they come on at 185 degrees and slowly increase as the engine heats up. When the AC kicks on with the trinary switch, they come on full blast.

I am trying to use the PCM as the controller as it has 2 outputs for it. Thanks Steve

You may want to talk to the guy that runs LT1swap.com. He is incredibly knowledgeable about this, and he knows which pcm will do what you are asking. His website is a mess, bit all the info is there.
