I'mplanning on installing the new harness tomorrow. I just went down to my garage to look at the new harness (still in the bag) that I bought from the dealer in December. There is a white sticker wrapped around the wires that reads "Delphi, MB part # 124 xxx xxx, FD 10/10/2008 ZD 07/09/1994" Obviously it's brand new and made in October of 2008. Just confuse the matter, why would they put a ZD with a 1994 date? So, I guess the replacement harnesses have both a FD and ZD?
