I have been to those links 100 times. If I have a hifi system will I also have fiber optic lines? I did a vin decoder and it said Hifi. Looks like maybe the two wires on the left went to a satellite radio module. The large black amp harness was right next to it right behind the rear seats not near the driver's side rear tailight like I have seen everyone elses.

I purchased a coding wire so that I could do some coding myself. but I was debating hooking up an OEM headunit somewhere else in the car, since I have lost the use of back up sensors steering wheel controls and seat belt warning noise with the aftermarket head unit.
