looking at the wiring, there is a large ) gauge blue wire and a bunch of crimp on connectors in there. None of that is factory wiring. Someone must've installed an aftermarket stereo, alarm or other and I would bet it has something to do with the faulty connections or undersized wires used.

Ya I noticed that too . Any idea what the green and blue along with the burnt wires are leading to? Looks like black connector is pop riveted up into gauge cluster ? And on second picture what is that motorcraft box for ?

You need to trace down and see where that aftermarket wiring is going, where it is is grounded, and what power source it is tapped into.

Ok I'll have my son check it out and see if he can trace it , problem is I'm out of town for couple weeks and I don't want to come back to a pile of ashes I think I'll have him bring it to a shop to be on safe side even though he said everything is still working properly . That's why I'm confuse over what the factory wires go to
