Thread: DIETZ headlight wire colors?

It depends on you wire harness manufacturer for the color wires they used. but the three prongs on the back of your headlight the one on the far right is high beam, the one on the top is low beam and the one on the left should be ground. my colors are green high beam, tan for low beam, and black for ground. your red and blue might be for your turn signal wiring. I hope this helps....John
