here is the diagram that shows the wire colors to the speakers this should help you finish this modifacation.
Thanks alot for taking out the time to respond. I may not have made my question very clear as to what I was looking for. So the picture doesn't really show me what I was looking for . Inside the HU, there is a CD slot and the CD slot is connected to the main controller box via a harness (12 pins or so) that hooks up from the CD slot to the controller PCB (all inside the HU). I was hoping to find out whic of those pins carry the audio signals from the CD slot to the controller board.
here are all the wire diagrams for the radio circuit. I think what you need will be in this post, I am posting the 2 diagrams separately so that they are separate. in order to give them to you in color I had to split the diagrams so when you print them out tape them together and there ya go. with the colored diagrams it should help you to identify the wires you need.
