Lets agree to use "Pump Coil "connections and "Wiper Motor" Connections. There is no pump motor. The pump is operated thru gearing from the wiper motor as you know. The pump is actuated via a coil/solenoid. It's gear is always turning but pump rod is not always moving. I think that's the general deal. Just so we don't get mixed up with terms.
The pump and it's coil are operated by one wire to hot and one wire to switch and sw is grounded on dash to complete circuit. I guess it's a push button on the wiper switch?
