That's not corrosion, that's fire. You need a whole body harness to fix it correctly. Like from the firewall to the taillights, including the underdash. Trying to cut, strip, and solder all those wires would take about a billion years. Of course to change out the body harness you'll need to COMPLETELY strip the ENTIRE interior, but that's still a better option time wise. I would also check the underhood wiring very carefully as well. It is extremely possible that there are lots of wires damaged from shorting.
