I don't know where to post this so I posted it here.
I found the replacement cable end for my Promedia 5.1.
I am repairing my Klipsch Promedia Din Plug that goes into the the sub. I have a replacement din plug and need help about the wiring.

According to this diagram where is my "black wire." I have all of the other colors but I do not have a black wire.
Three wires are wrapped in a tin-foil material. One of them being a bare no plastic wire. The "yellow" and "black/yellow" wires are along with the bare wire inside of tin tin-foil wrap.
Outside of this tin-foil three wire wrap are the other colors plus anther bare wire. Am I suppose to solder one of these bare wires to the shield? And the other being the "black" wire (even though it is not colored black?)
Some guidance would be nice. Thanks.
Please help
