GM/crysler/generic has them for single fans to control the speed as needed.
It can wire directly to most ECM modules and do what your asking nice and clean.
search for your model of ECM add PWM and fan wiring and a lot of sites especially on LS swap sites have all the pins wires you need.
You don't even need the fancy expensive corvette model there are some basic ones that work well .

I think is a 411 it is the stock unit used on 05-06 silverado. I am trying not to add any other controllers just let the stock pcm do what it needs. Thanks Steve
