I dont know what they did on your model year, but on my '88 126, I was able to take the switch apart, and free the two (I think) wires that needed to be freed. Luckily, the wires and the holes that they belong in are numbered.
I agree that they could've put a plug in there though...they do it for other stuff, why not for the window motors?
