EBay.

Just picked up one for my 94 cabriolet for $135 including shipping and cartridge. Works well.

I think you have the last year of the wired in style. Check in the trunk for a cable that has a rectangular plug on the with nine wires.

Application was pretty universal, units are the same, the mounts can vary between the class and body. I'll have to fab up an adapter, but it's pretty simple stuff.

Here's the blurb from the auction I won:

This will fit a:
