I promise that this will be my last question for the day, but does
anyone know specifically what each of the three wires accomplish on
the wire connection.  I don't have the wires in front of me for the
color scheme, but the motor itself has the connections labeled as 1,
2, and 3.  I'm guessing one of them is 12V+ another is ground, since
the thing is mounted in rubber, and maybe the third is some sort of
signal that turns on the motor, but anyone know which is which?

TIA
