Specific Pin functions?

Can anyone tell me what specifically the certain pins are on the C3 plug in the back of the REQ radio? My C3 plug has wires on what appear to be pins 20-22. I looked at the list and it just says:
20Dark Green / WhiteAUDIO RIGHT 1 21Dark Green / Light BlueAUDIO LEFT 2 22Dark Green / Dark BlueAUDIO RIGHT 2

Although the wire colors dont match, I am pretty sure those are the pins.
Its the bottom 3 pins on the left side looking that the end of the plug.

What specific object would those wires run to? Rear Audio jacks behind the console? Something else? The jeep has none of those jacks anywhere and I am just wondering if it is purely just pre-wired. Assuming it has no current function, I would like to unplug that connector, buy a aftermarket plug and wire up so I can output video from the REQ to my headrests.

Thanks for any help.
