Sorry Marc I don't have one for sell. I was trying see exactly what you were asking for because I see the nos radio wire quite often on ebay if I spot it again I'll pm you a link.
You're killing me! lol
If you do see one please email me and let me know. Otherwise I am looking at pieces (connector) to complete the project. If I find a connector that will simply work I am going to use it as it cannot be seen anyway.
