Broken FP wire leads

[Tom I]

Question for the masses:
We are using a Fisher Price motor with our robot, and we ran into a little snag...

(now that you're done scouring the picture for our design )
The motor on the left is the one attached to the robot, rather permanently, and as you can somewhat see (sorry it's out of focus, bad camera), it's kinda missing some connection leads. The motor on the right is the spare we have with intact leads, ready to be swapped out if needed. Now begs the question... do we need to? Do[es] any team[s] have actual experience with soldering to a broken lead of a FP? My initial thought was it can't be done, but it would save a lot of time and our spare motor if we were able to use it as is, because the motor is semi-permanently attached.

Take-away: When people say "add strain reliefs to those motor wires," actually add strain reliefs!
