audi a8 headlight help
 

Hello all, much thanks in advance if you are able to help me. I need to figure out what wires that go into the passanger side headlight plug are the ground. I can put a meter to the pins and find high low running ect but can not find the ground.

Any help would be greatly appreciated.

A little more info. Have replaced ballast, swapped lights and starters but cannot get passanger side light to work. Appears that the wiring has been altered and im trying to see if the plug going into the light is done correctly. I have found a pin that has low voltage at 8v and one that has jone at all. Only the hid is not working, running, blinkers, and flash to pass are fine.
Any ideas or suggestions would be great.

There are three brown ground wires.

Any Idea on what number on the plug they are supposed to be?

1, 3 and 7

Excellent, thank you very much.

Do you happen to have a diagram of the plug that shows all wire locations?
