Hi Everyone,
I need some assistance in identifying the plugs on the Fakra connections on the back of head unit.
I have search all over and don't seem to find my model of outputs. It seems I'm missing the rear outputs for rear headrest?

I have a quick picture I hope someone will be able to identify. (Sorry it's not too clear)

The two green on bottom believed to be; the left is Rear Camera and right is Aux In?

Also what is the 4 pin yellow plug diagram?
I'm looking to input sound and video to the unit along with needing to know which is video out so I can feed video to the head rest?

Thank you for your input,
Let me know if you need more info?

Just in case someone needs to add video to a similar head unit, the green plug in the picture is video input.
From picture the right fakra is aux video source input (installed ipad airplay mirroring/chrome cast)
The left is back up camera video input.
