    @whitequark If I were making this I'd be tempted to use metal quick-connects, add a bonding wire between the jacket-side quick-connects, and then wire the pack-side connects to the power supply and enable input such that plugging in the quick-connects starts the pump after a few second's delay. You'd want a plastic bracket for the pack-side connects to ensure they can't complete the circuit by touching each other

    @whitequark alternately a pressure switch with an activation point below the maximum pressure of your pump would work (I think the ones sold for reverse osmosis units would be a good match for your system). If your pump doesn't have check valves you could add one before the switch to keep pump backflow from causing constant short-cycling
