Does anyone have a diagram for the fiber optics loop?

im trying to diagnose my PCM issues. Seems like light is reaching either the CD changer or amp. But doesn’t make it to the dvd player under the passenger seat.


I still need to remove the cd changer to get check that connector as well.

trying to find some kind of repair manual on eBay with electronic delivery. not having much luck.

I ordered a fiber optic termination loop plug that completes the circuit so you can bypass the cd changer/nav/ etc.. to test which one is making an error. In my case it was the XM unit

Please share, I've got a radio/PCM issue and it decides to work at times and not, screen loses the station details on XM (or will be stuck on a channel but you can change stations, but the display doesn't reflect it), volume will stop randomly one day and fine later in the same day, completely bat**** crazy. I need to get a reader but haven't decided on which one yet~
