The date tag is on your harness - and it shows a 1993 year, meaning its an original one from the factory. My car has a later one and is dated 2004, still in very good shape.

I have however rewired some E320 harnesses and E300 harnesses by reusing the old connector cases and lugs - the old MB harnesses are relatively easy to work on compared to new models. Its not a good idea to do this as your first harness rebuild project, if it is then get some supplies for marking and writing down whats what and take lots of pictures.
