FIRST of all, the fact that your team found this forum is really good. Our team didn't find it until our second year out, and we would have been so much better off if we had seen it our first year!
I couldn't get to the youtube video you posted, so I'm not sure how helpful this will be.
Team 2980 has gone completely open source. We would be happy to share our CAD files as well as any pictures or information on how we are building our robot in order to help other teams, especially rookies.
Here is a link to our thread.
We will also be posting tutorials on our robot over the next week. Especially relevant is how we mounted the windshield washer motor.

There are pictures showing how to make this on the above mentioned thread.
Finally the connectors for the window washer motors. Another person posted a link to where to get them on this forum. The website is
www.mouser.com and the product number is 829-12129487. That is for the plastic shell. There are also little metal pins that you have to put in there. 12129493. The total cost for these connectors will run you about $2 a piece.
If you have any questions feel free to contact us via PM.
