I am replacing a Jacuzzi Magnum Force 2 speed pump and motor with a Whisperflo 2 seed pump and motor. The new wiring is my concern. The old pump had a wall mounted switch where up was high speed, middle was off and down position was low speed. The new pump has the 2 speed switch mounted on the motor. What would be the easiest and most sensible way to wire in this new pump?
