I've purchased some Sugru and plan to try reinforcing my NC charge cables. I tested it on another connector, and it provides a strong yet flexible shroud. It might be a good middle ground. I'll be able to test this weekend.
Here is my picture of circuit board. The contact side of the pins that fit the NC connector would be facing downward on the right. Sorry if it's not quite as clear as it should be. It was difficult to line the camera up exactly by hand. Also, some of the plastic has been cut away near where the pins have broken in order to get a better contact with my multimeter to follow the traces on the board. My schematic is almost finished, and will follow soon.
