No electrical at all

When I get down under the steering wheel and found the wires coming out of the back of the bulk head connector there is one wire that has melted and it is blue. The copper wire is still intact but most of the blue plastic, rubber insulation is melted off. All the wires coming from the back of the bulk head connector come together in one big roll with what looks like black tape around them and the melted blue wire was to, but it seperated from the other wires when it melted the insulation.

I am completely lost. Is there anyone on here near northwest North Carolina? If so are you interested in repairing this? Of course I will pay, cause no one around here seems to even want think about looking at it.
