Adapter??

I bought the expensive adapter for the active boxes. Unfortunately, the cable assignment is not quite right. If I listen to the radio, everything is fine, unfortunately not on CD. There are only the front boxes running, the rear ones only run when I have traffic radio on in the background.
So I guess I'm gonna have to reconnect the remote cable.
Who can help me and can tell me the name of the Audi cables for the rear boxes (red plug) matching the associated colors ??
