another wiper motor / switch question

I would prefer switching the motor to a 3 speed / variable setup as my crank arm is for that apparently. I'll snap a photo tomorrow to check.\

Does the 2 speed switch integrates the push function for the washer system or is it a separate button on the dash then?
Would it be possible that the resistor in the Cardone motor is integrated into it and doesn't need to be added on top?
