Well, once again, without photos it is tough to say. At the very least, I would do some troubleshooting. Look at the wiring diagram and figure out what they go to. Then check that component to see if it has been replaced. How do you know what the wires look like inside the harness?i think there is a good possibility this condition is the result of a short circuit. Perhaps they are melted like that all the way to the component? A little rubbing around and you could easily have a fire on your hands. Sure would be nice to know what would be the likelihood you are to have a major catastrophe on your hands
