I have wires that run into my carb that also connect to an electrical post on top of the water jacket. I am re-wiring the thing with a PAINLESS SYTEM and this wire is not included, can I just hook it to another power source that is a keyed on source, or does this wire originate from the instrument panel or something. I have a 86 so its not computer controlled per say. I think the electronics going into the carb is called the Carburator Air fuel solenoid. Thank for the help guys, this thing is my last hurdle to having the wiring finished.
