I don't know what 2980 has done, but one of the allowed modifications is to the connector on the window motor. If you like, you can cut away the plastic and solder on more conventional leads (R47D). A little shrink wrap and you should be good to go.

Team 2577 has had good success with crimp-on quick disconnect terminals. Using insulated terminals and a bit of electrical table, we've never had a motor connection come apart during competition. Just make sure that you have a good ratcheting crimp tool.

As to polarity: it is a motor. Test it. Hook it up with clip-on leads on way and see how it spins. The window motors are slow enough to see easily which way they are turning.
