It is supposed to lower the voltage to the pump at low RPMs, and run full voltage at higher rpms, but I don't think it works right. I just used the factory wiring to switch a relay in the trunk powered straight from the battery. Went from 10.8 volts to 13.1 volts. I used big wires too, so now that I'm running two pumps, all I had to do was mount it basically.
