Still bubbling out overflow after changing water pump, thermostat, radiator,hoses??

Leave that one alone. It is designed to “break” under to much load. For some reason, it didn’t this time. The other wires took the load and burnt out.
The plug cooked on the fusable link wire.and cooked the insulation and plug on inside of car firewall..and the big guage black wire burnt up..those 2 are the worse ones other just look a little effected from those 2.should I just cut the wire as close as I can to the plug and use the rest of wire that says fusable link
