What's the other stock radio harness for?

At the back of the stock radio, there is the big 24 pin grey connector, and also a smaller 12 pin black one. What is the black one for? CD changer option? I couldn't find it in the service manual.Thanks!

Well yeah, I figured as much, but it looks like 4 of the five wires are for the XM satellite option for digital radio, so I don't need it. There is one wire for "Mute control" in that connector to the amp, but I'm not sure if I need that for basic radio operation (I don't have XM or Onstar.)

I'm all hooked up and the new JVC HU sounds awesome! I didn't use any of those wires in the extra 12 pin back connector. Not needed.
