JDM Auto climate control

Anybody successfully install one of these? Im assuming that the only problem would be with the hot and cold lever thing. I have the auto climate control and the harness but i dont see what will move that thing to make the heat or cool air work. Anybody know how to do this?

found most of my answers

Since my car does not have AC lets say i just want to have the heat always on and all i need is to make the fan work along with the contol that controls where the air blows out> How hard would that be? do i still need a sun sensor and various other parts from a 180sx?
