In the S2000 trunk, behind the fuel filler lines, is an orange connector for the CD changer. Honda does not sell this part (as far as I know) separately - they only include one half of the connector with the whole dang wire harness, and the other half comes with with CD changer. I need BOTH parts, on their own. Is there anyplace that sells these sorts of OEM connectors?

You can see the CD changer half of the connector in this parts diagram.

It's a long shot maybe but try installer.com
You may have to call them, but they have always been very helpful
