When did Ford change the design of the COP plug? I went to change out the broken connectors on my car, but found the new plugs are different. The metal plug on the old plug is a smaller square. The replacement plug is more rectangular. So naturally I'd have to change out the pins as well. But I'd rather not do that if possible. I ordered these replacements months ago planning for the next plug change. So naturally I don't have the part number.
