I have a 1982 300SD, and need a passenger side seat control switch. Can I use the seat switch, from the newer W126 based cars? ( the one with the memory function, and 1&2). Of course, I neither expect, nor want the memory function to work.... Just the basic func. that comes with the 81-85 W126. Will the harness fit? Will the trim, etc, fit ???? Thank you in advance.
