Wipers, 3 speed switch with 2 speed motor

Just wondering if anybody knew if a three speed wiper switch would work right with a two speed wiper motor setup? Obviously I would still only have 2 speeds since that part is in the motor itself...right? I know it will plug up, but I haven't tried it since I took the wiper motor apart and repaired it, kind of afraid of messing anything up. The reason I ask is because the 3 speed switch has the push function for an electric windshield washer motor and I believe that would be pretty convenient.
On a side note the dart is about ready to hit the road, all I need now is an alignment and it should be ready to go. It still looks awful, but if all goes well I'll be able to drive it to monster mopar weekend this year.
