Hello,
I was wondering if any of you would be able to help me... I have changed the Head Lamp Assy's on my 2000 S430. I have installed the new Xenon Head lamps with automatic leveling system. The main plug on the head lamps plugged in with no problem and all lights work....However on the new head lamps there is another pigtail with 4 wires for the automatic headlight leveling., being that my car did not come with xenon head lamps the car does not have the additional plug for the leveling system there is nothing to plug the additional plug into.

Could someone please tell me what the 4 wires are for.....power ? ground ? ignition voltage ? battery voltage ? ...etc The colors for 4 wire plug are RED, BLUE, WHITE and BLACK..... If I would know what the 4 wires are for,then I can make it work .....
