It's been a while since I've had one apart so I could be wrong, but I believe the dash switch is different but the wiring is the same between the non-recessed park and recessed park setups. The dash switch doesn't do the parking though, that's handled by an internal parking switch and cam inside the wiper motor that parks the wipers when you shut them off. And yes, the motors are totally different between the two setups.

And you're correct, the cars with recessed park wipers have a taller stainless windshield trim piece that sits about even with the hood and fender line. If I was putting an aftermarket non-recessed park wiper motor kit on the car I would switch to the shorter stainless trim piece for the cars that didn't have recessed wipers, otherwise the wipers would probably jump up onto the taller stainless trim piece at the bottom of every stroke.
