I'll take it Aaron! I already have a hole cut

I have cable, etc already. (I don't mind if you'd like to give Rob first shot)

If you already have a hole cut it's probably too big. You might have to wait until I have time to make one to fit.
What are the dimensions of the hole and is it square?
Aaron
P.S. The tray doesn't come with cables and terminals, that is $24 extra on top of $45.
