Also, you can hook wires up to it by crimping on the female end of a spade connector (very cheap at any radio shack - $0.05 a piece).

(Note this may not be the exact one you need - it's just an example)
Bend them slightly closed with a pair of pliers so they're nice and snug on the motor spades (these are the 2 prongs that stick out inside the white connector). Slide them on.
Then wrap your wire in a loop and zip-tie it to the white housing for strain relief.
Now when you burn up the motor, or need to take it off, you aren't cutting and resoldering.
