it would say on the wires more than likely which is what and if not go buy the harness for it and save yourself time and hassle. Why do you need the color codes anyways?
o and as a side note, the EB edition has an external amplifier IIRC so you need to trace the wires from the amp which I believe they are on the right side in the back.
WELL WHEN I BOUGHT THE EXPED. THEY HAD DISCONNETED THAT BACK AMP SO WE WERE PUTING IN INFIN.AMP AND SPEAKERS BUT NEEDED THE REAR COLOR CODES FOR LEFT AND RIGHT
