Yeah, I cant imagine it would be that simple. I really dont think it would work without at least changing the cold/hot flapper control, because I assume the auto one doesnt have a cable control. And all the other flapper valves are vacuum operated, and I cant imagine the tubes would just hook up to the new one, its gotta be electric.
I'm going to leave that can of worms unopened I think. Although, if the controls were electric, I would be interested in controlling that from the car computer, I've seen it done before and its sweet
