Wiper wiring

I'm replacing my wiper switch with a push button switch. I know that will only give me one speed but that's fine with me. I dont drive the car in the rain as it is but still want a wiper just in case. So heres my what I need help with. It's a 2 speed motor and need help with what spade is for high, low, and ground? Is the park feature part of motor or is it part of the switch? If it's part of the motor how do I wire it so I dont have to play the on off game. 72 demon
