Multifunction Unit pigtal

Have been experiencing a variety of interesting electrical issues. Traced it back to corrosion on the MFU. Trouble is, one of the wires from the harness broke off and others have visible corrosion. I got a replacement MFU, but need to repair this harness. Anybody know where I can get either a pigtail or what type of connects go into the harness?

Thanks. The problem I am having is with the MFU behind the fusebox. Alot of corrosion in the black pin connector that plugs into the MFU. It is this black connector that I need more info regarding connectors, etc.
