There are several vacuum lines running to the heater controls, for both the electronic as well as the manual versions. Each is used to position different doors in the ductwork, i.e., defrost, vent, floor, etc. The best thing you could do for yourself is to acquire a good manual, such as those offered by Helm, Inc., out of Detroit.
