Replacing a booster pump in a RO unit with a Aquatec 8800 24V, repining the the different pigtails isn't a problem and the old power supply/pump were also equipped with red/black wire leads- the Aquatec has both black leads. How do you identify the positive wire?

Simple DC motors can work in either direction. Connect it to power and if it rotates wrong direction - reverse the leads.

It’s 24 volt AC usually. So no positive or negative.

Edit

I just looked at that model and it is an AC pump make sure your power supply is 24VAC

Thank You

pump Model 8841-2J03-B421, 24VAC
supply 24VDC, 1.2Amp

There are so many models of pump that I mis ordered- was supposed to be DC, BUT Aquatec thought my pressures were good so were concerned about the 1.2amp of the previous pump demand. I unplug when not in use. The current power supply powers the RO controller so will continue in service.
