Yes, the engine wiring harensses on 1993-1995 E320's are all bad. Do a search on "wiring harness".
The original head gaskets also had a bad design, and leak oil externally at the right rear corner of the head gasket (passenger side).
Yours has probably been replaced if it's not leaking now as the original head gasket probably couldn't make it this long.
The good news is that the new wiring harnesses are good, and the new head gaskets don't leak.
