im not sure i would just splice them all together. theres a lot more wires than in the older model car. i have no idea what the other wires are for. this may sound silly but, did you check both bulbs and make sure that theyre both good? if one headlight goes bad they both go out. you could also check the harness where it runs behind the drivers side fender. its been known to rub through the wires and ground out. i might be out of ideas after that. sorry im not great with the electrical system.
