Hey mate.
The parcel shelf will come out once the rear seats are removed and a couple of retaining trim clips are yanked away.
Remove the rear lower seat and unbolt the upper seats and remove. If you have 3 piece upper seats, just fold down the centre one.
There will be a couple of trim clips and maybe a child restraint bolt holding the shelf down.
I don't think I have ever removed one from a VS but that'll point you close enough.
I can't help you with the wiring diagrams as I don't work at a Dealership any more.
PDF is great and that's what our computers were set up for but copying them I have never tried.
I'm not sure how good the Gregory type auto manuals are for wiring diagrams.

What are you mainly after? Head unit wiring or other stuff? Perhaps try one of the insanely large car forums.
