I have an odd question?
 

does anyone happen to have the wiring diagram or a diagram for the wire connector to a honda optional 5 disc changer.

im not talking about the regular connector ( speaker wires, antanne, 12v, ground etc) that connects to the back of the cd player,

its the connector on the left in the picture that should go to an external device, such as the honda cd changer... its for an experiment Thanks!!
