I didn't break them. The outer plastic cover is separating from a terminal and opening up along its seams. It is exposing the shielded white wire underneath. The point of attachment must be weak or something, as I haven't been messing with the cables at all.
So, while everything is functional so far, it would appear that the cables only made it about a year before starting to self-destruct. I'll probably have to figure out how to just make my own. Or, maybe I can just re-terminate the stock cable somehow.
