Sorry about the previous post but I didn't fully read the ECS description of the product to begin with. I assumed it was the automatic leveling system for the OEM HID system, which has hardware on the rear suspension tied into the headlights. What is being referenced in the link you posted can be and is used for incandescent lights. You will need the switch for your dash, which is incorporated with the dash lighting switch, two leveling motors for each headlight, and the harness you linked to. Most VAG headlights have a dummy plug installed where the leveling motor will mount on the rear of the headlight. All you have to do is twist the plug to remove it, detach it from the reflector, and install the leveling motor in the reverse order of the plug. Just be careful when trying to fit the leveling motor into place as you can push to hard trying to snap it in and pop the reflector off of its other retaining positions. I don't remember if the leveling motor comes with the O ring gasket but if not you should be able to use the one from the dummy plug. Good luck.
