Cool. Thanks so much for the help. There's only a small 3" section that's marred, it seems. I have no idea how it happened. Maybe wearing against the hood? That particular section of the wiring does ride high. I bet it just rubbed raw.

I guess I should have thought of the simpler repair tips a while ago. I tend to be single-minded and sorta dense about certain kinds of logic. Asperger's, I think. But that's another story....
