Greg, the heater control panel is supposed to light up as mentioned by Steve. It has a single feed wire/bulb that goes into the side of the control unit that provides the light.It is grounded to the metal dash as it is bolted to it.Same goes for the lighter as it has a single feed single feed wire.The highbeam housing also has the single feed wire that is grounded with the strap.I'm not positive but i think you could use a metal coathanger to form a strap if you don't have one.In my reply above i mentioned seeing different straps and it looked like a metal coat hangers diameter +/- with a looped end for the screws and was bent/routed in the same fasion as the flat one in the picture i took.
