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.
