Hi cara,

Yeah, this be the place. It helps if you post a link. But I just used google. Found this:

The ME1002 is a Series Wound DC motor perfect for lite trucks and small car EV conversions.

It is not the usual terminal marking for series DC motors, but I think I am making a pretty good guess. Hook F to AA. Hook FF to one battery terminal. Hook A to the other battery terminal. Battery polarity does not matter. If you need to rotate in the opposite direction, hook F to A and FF and AA to the battery. I assume A and AA are the armature terminals and F and FF are the field terminals.

It is a series wound DC motor, so it has an extreme no load speed at rated voltage. Therefore, when running the motor with nothing attached to the shaft to load it, use low voltage, like 12 volts. Even at no load, it will draw a large current spike to get rotating for a short time. And then settle into maybe 20 to 30 amps running. So you need a healthy power supply or battery and wires to handle that current.

Be careful with that thing.
