The motor will have wiring diagram and voltage on nameplate.You can re-post question with information that shows on nameplate for more exact information, or keep reading below:If motor is rated for 240Volts, then it will not work with 120V.If motor is rated for both 120V and 240V, then either Low voltage or high voltage will work, and one wire will be common, and 1 wire will for 120 and other wire for 240.If motor is rated 120Volt two speed, then one wire will be neutral, and 1 wire low speed, and other wire high speed. You can connect your wire to either low of high, and cap other wire.If motor is 240volt two speed, then one wire will be common, and 1 wire low speed, and other wire high speed.If motor is rated 3-phase, then all three wires are connected to the voltage shown on nameplate.If motor is rated 3-phase two speed, you may need electrician to wire the motor correctly.http://waterheatertimer.org/pdf/AO-Smith-motor-wiring.pdf If you need further help, I’m available over the phone at
