I have four wagons in my shop: my '82 daily driver, a 1980 being converted to a turbo-stick,
a customer's 1983 "greasecar" conversion, and a 1985 for parts.
Unlike the other three, the 1983 has aftermarket window switches, the kind
that sort of "explode" when you try and service them, and thereafter -- plastic
housings and metal tabs, everywhere. The replacement switch is on the right.

I'd like to restore this car to original window switches, like the one
of the left, above.
BUT, the pin plugs are a different size! AND the orientation of wires in
the housings differ. Even the number of connectors on the back of the
switches is different!
I've looked in EPC, but there is no record for any "one year special",
using a different switch and harness layout that I can find. I haven't torn the seats out,
but here's my question:
* Did these aftermarket switches come with some sort of sub-harness
that adapts the switchgear to the smaller pins -- and layout?
I see no evidence of a sub-harness, but haven't gone "inside the console"
to check further -- yet. The only record EPC shows is the switch on the
left: A 000 820 82 10.
I sorta doubt that M-B would change pin sizes from the "standard" 4mm.
I can't find a 1983 wagon schematic, but the 1980 and 1985 are substantially
the same circuit, unike what I'm seeing in this 1983 "weirdo".
Ideas?
