Replying to my own post. How lame is that...?

We had our arm not operate TWICE during the tournament when someone other than our Designated Electronics Guru and Cable Guy tried to plug in a PWM cable. We lost both of these rounds, but found out that we could really play defense. It was kind of fun watching our modest little wooden bot keep a 12-foot topper from scoring a single tetra, even if we still lost the match.

Of course, the real failure was that we did not detect the bad connection before the match. We bad, the 'bot was sent out to the field without a complete systems check first. This will NOT happen again next year. Note to self: if anyone is working on the robot, the electronics Guru will be the only one allowed to touch the hardware.

A team at Portland (I forget the number, but it was Santiam Christian School's team) said that they put a tiny dot of silicone adhesive on the connector after it is seated. They say the silicone is easy to remove, but grips just enough to prevent accidents.
