I mounted a 12 volt drill with a spade bit to interface to the bottom of the computer to drive the pump. It is not wired to a switch, but rather to the electric reset that told the original pump motor when to go. When the pump handle is turned on the computer resets to zero, and then the 120 volt to 12 VDC power supply gets power which starts the drill going which turns the computer.
