I have this unit on the workbench to work on the CD changer, which acts as if it's stuck. Evidently, Ford had tons of different versions of the 6-CD changer. I can currently operate this unit from steering wheel. I really would like to fix it, it I can't seem to find this pinout anywhere. The models vary from year to year, and month to month.
Ideas?
