Mann, I cannot find what I'm looking for..

Is there an interface out there for an analog input to can bus ac signal so the pcm can operate the ac like factory? I'm no amateur google searcher but havnt come up with squat!

There's a company called MoTech that makes a CAN module that, among many other things, claims to allow AC control. I have no experience with any of their products, but a local guy that primarily does Jeep swaps uses their stuff to make many of the Chrysler modules in a new Jeep play nice with the LS/LT engine controllers.

I think he's on here too, but I know he's on LS1TECH, his user name is vannatta20. Might try messaging him.
