If you mean the wire I'm thinking about, it is a positive link from the battery, to a terminal on the right side of the fender, across the radiator support and connects to the alternator.

Mine melted one morning.....when the unrestrained wire got against the header on the driver's side and shorted out. If you don't have anything else to use and your mind is racing about how much of your truck is going to remain after all of it starts to burn....you'll pull the glowing wire apart. After some time, the wounds will heal and your hand won't be as tender any more.
