Hi All,


The question I have is, I have a 2004 Allroad that has the auto leveling lights. How do I know if it is a 3 wire or 4 wire. The reason that I ask is the headlights are from another car. I am looking at buy new head lights and it ask if they are 3 or 4 wire auto leveling units. So I am not sure.


Thanks for the help
