Can any one tell me what the two lower wires are at the rear of my 6000cd.. my car has no phone bluetooth or aux fitted...but i would like to connect aux ,the ford fitting on ebay i think goes the location where the wires are

The Aux socket plugs into the empty space to the right of that lower block.

That left hand socket is steering wheel control (SWC) inputs to the radio.

Upper wire is SWC signal input (pin 6)

Bottom wire is the SWC ground wire (pin 8).

On the Aux socket the block will connect to pins 5 and 11 for left and right channel inputs and pin 6 for Aux ground wire.
