Motherboard port confusion after Top Screen Replacement

Hello, I have the 3DS XL taken apart and the upper screen replaced. I am now ready to reassemble the two halves of the 3DS but I lost track which ribbon cable is the right input to the motherboard.

I see P6 and P9 labeled on the MB inputs and just need to know which is for the screen and which is the camera. Or if it makes it easier, which ribbon is connected right next to the speakers? It is not 100% apparent in the tutorial.

Thank you
