Yes, definitely plug and play,. the only thing you need to do is source a bigger gauge wire from the alternator to the positive battery terminal. some people chose the 140/150 amp from the mid 90s S 500, the reason I chose to use the 120 amp from the S 600 is because it was cheaper by about $80. I'm guessing there probably isn't a difference either once you get over a 110+ amp alternator because even at idle I'm cranking out about 13.8 - 14v.....with a full load I still put out about 13.x - 12.5+ v.

I'm a huge fan of the all black look. Actually I credit the theme of my all black car to forum member oldsinner. He has a black/red w140 and that is my favorite model/body style of all mbz.....that and the w211. I made the homemade projectors/hid lights to further make it stand out which I get a lot of compliments on. Even from enthusiasts that prefer the all stock look have given me complements. huge difference in light output as well.
