How to identify which Wiper Motor (2 speed or 3 speed) Should be on 75 Duster

I've been trying to figure this out. When you push in on the button it feels sprung, but I've been told that the answer is no. The car I'm working now had a 2 speed and a manual foot pump for the washer. I've been working with another member to convert the foot pump to an electric momentary switch which I will wire to an electric washer set up. Seems like the best of all worlds to me.

Just to maybe help you. This is the 2 speed wiper motor switch out of my 74 Ramcharger. Part Number 2864152 When You push it (about a 1/4 Movement at most) It triggers the electric washer. Then of course there are 2 clockwise positions for Low/Hi on the wiper speed.
