Warning:

***On some systems, the middle 2 wires on the motor side are swapped. This is easy to fix by slightly prying back the white nubs and swapping the wires. Otherwise they work fine.***
Make sure the motor connect to a constant current or chopper drive controller before you test motor.
Connecting the motor directly to a power supply will destroy the motor.3
