New AMERICAN(nas) style heater help
Putting new heater and controls. My question is that both the heater connector (3 pin type), and the control harness connector (3 pin type) have two wires in common Green/Yellow and green/gray, but the heater end has a power lead and the control harness pin has a ground. I assume just connect the like wires for fan speeds, but can I just hook up the hot to a fused lead and the ground to the chassis? or is it more complicated than that?
