I am trying to find a diagram that describes the wiring harnesses on the back of my '04 LS Sound System. I have the Premium Sound System with 6-disc in dash changer. I am trying install a Parrot CK3100 Bluetooth Hands Free Kit.

I have found a couple of references to wiring diagrams, but most were for older LS's. I have seen other references that indicate something might have changed for the '04s.

Any pointers?
Thanks,
Steven
