oN MY 69 GTO , WHEN THE LOW BEAMS ARE ON , THE HIGH BEAMS COME ON DIM. i TRIED GROUNDING THE WIRES AGAIN BUT NO DIFFERENCE.
i ALSO REWIRED THE HEADLIGHTS THE SAME AS FACTORY ( FED THEM DIRECT FROM BATTERY) AND USED THE EXISTING GROUND WIRES TO THE BATTERY BUT NO DIFFERENCE(ALSO TRIED GROUNDING IN OTHER PLACES). WOULD IT BE THE LIGHTS(SYLVANNA BULBS), OR MY HARNESS. tHE OTHER THING IS THAT MY WIRING DIAGRAM(FROM FACTORY BOOK) DOESN'T EXACTLY MATCH
THE HARNESS ON A 69 GTO.
ANY HELP WOULD BE APPRECIATED.

Have you tried replacing the highlow switch on the floor? These sometines go bad and can cause your symptoms. They are real cheap
and will take about 20 min to replace.
