Don't forget to carefully curl the wire back toward the front of the motor and secure it to the motor case with a tie wrap to prevent it from wiggling around and snapping a contact off the motor.

I would like to add to this that soldering these motors, for the very reasons that fox mentions, can seriously damage them. For this reason, I would suggest that you only resort to soldering in a last-ditch attempt to get a connection. In the past, when we soldered these motors, we found that the only effective soldering tool to use was a
200W soldering gun, as anything else would simply drip solder onto the terminal without solidifying the connection.
Properly stress relief-ed 3/16" QDC terminals (available at your local RadioShack or electronics supplier) held in place with hot glue (be careful not to block the armature vents!) will hold up perfectly fine. You may want to look into getting flag terminals to facilitate stress relief.
@jessica, ring terminals work fine in the right application; I assume you will be using them on the speed controller end to tie them into the M+ and M- terminals, and they work just fine for that purpose (provided your terminals are designed for #6, or at worst, #8 studs). Just keep in mind that ring terminals limit serviceability (if you ever have to replace the connector, you'll have to take out the entire screw to do so).
