Persistent rattle in rear passenger C pillar

Yeah i need to check the sunroof tracks. Last step would be to remove the rear passenger door card. Even when the sound seems easy to localize, it could really come from all sorts of places.

So my rattle went away on the entire drive home yesterday. Two things, I slammed all the panels back home. Trying to at least see if the rattle changed, or some clue would arise from that. The other thing, I remembered I have Baja designs wiring and plugs between the bed and the cabin. One of the plugs was free to clank around, I positioned it such that it may not clank around anymore. So my issue could have been exterior of the cab. Ill need to come up with a more solid way to baton down that light plug.
