I currently have a good source for Xenon take off headlights for 140 S class mercedes. These were removed by the dealership and are original equipment. Aside from the headlamp assemblies themselves, would I need anything else to fit them to my 1993 500SEL? I don't assume the wiring is "plug and play" and the seller has told me that for another $300 or so he can get me all the "stuff" I need to install it...I assume that means the ballast/leveling parts? If anyone has any information on this, please let me know. Thank you.
