2nd picture, 12-pin connector at top of picture is from the CD changer. It plugs into the radio unit. The radio unit is the one shown in the 2nd and 3rd pictures. In the 3rd picture, you can see the empty slot in the upper left. Sorry, wish I could help with the rest, but don't know what those are.

 

could be for the tv module. Get a subscription to GTR to get all information including bulletins and Connection locations and pictures and directions and wiring diagram. Those systems are all connected together and one one goes down sometimes it will all go down.
