It's just the plastic housing. You should be able to remove the pins from your old connector and reuse them if they are undamaged. If you need them, 82998-12440 is the part number for the wires with the female pins on the end of them for that connector, but you would need four of them and they're each almost as expensive as the plastic connector.
