Ed, thanks for the thoughts but the headlight wiring is a separate harness from the engine harness and I am just trying to come up with what would be different on the engine harness. The engine harness connects to the distributor, blower motor, alternator, temperature and oil pressure sending units and the A/C compressor. That is why I am thinking that part just might be the same as on the Skylark GS. Any and all thoughts are appreciated.
