Satellite hook up inside

[RuffRider]

My manual for my 2017 flying cloud says:
the interior pre wire, consisting of a 2 pin power ground connector and a coax pigtail located under the blue ray. I see a blue ray but I don’t see how to get under it and the only pigtail is a USB port. See photo. There are two plugs coming from the wood box. I know one goes to the blue ray but does anyone know what the other might be? Does anyone know where this ground connector and coax is?
Thanks!

Might want to checkout my long ongoing recently posted threat. I actually thought that was my photo, almost same question too.

TV: USB dongles/faux outlets?

There’s a good YouTube video of a guy taking that box apart, which apparently has to be done...and some things purchased, yawn.
