If memory serves me correct, the 98 and newer OCP (overhead control Panels) can't be put into a 96 or 97 due to the circutry.
The 98+ units are on the interior CAN bus and are a computer where as the
older ones are switch groups.
Sorry for the bad news.

Think the dealer is expensive? Do you know how much it costs to train a dealer tech? Or buy the required MB special tools to have on hand?
