this is a long shot, but i need to replace the section
of the wire harness that plugs into the back of the
stereo unit in my E. The section with the the 20 pin
connector. Does any know the part number or has
had any experience replacing this part of the wire
harness ? :oops:

Call this place to be sure, but it's likely one of the harnesses in the top left part of the diagram at the following link...

Hope this helps!
