The 3rd wire is no doubt feedback to the controller & not needed if running at full bore without control circuitry.
Hey Mike, is there a way to figure out what the polarity is without damaging either the pump or power supply? Can I just plug 2 wires coming from the power supply to the different combinations possible and see which 2 work? Are the only 3 things that will happen be 1) the pump run backwards if the polarity is crossed, 2) not run at all or 3) run properly?

Or can I smoke something by just trial and error?
