I saw my low beam headlight out. I decided to replace them all Left and right from Halogen to Fahren LED's. The removal and replacement went smooth. Now I also noticed that it was both the high and low beam on the left side does not work, the right looks great. I've searched for a wiring schematic... I checked the fuses, and swapped out relays. Is there a common ground that both the left high and low beam share, and if so where is it located? Thanks in advance!
