each installation I have seen is a Cut and Fit, Heat and Bend and paint to match. There are so many different TV's, Surround Sounds, satellite, etc systems, a fool proof point to point is pretty much non-existent. Your best bet is to hire one of the local techs from one of the A/V dealers to come out and hook you up.
I can usually look through all of the manuals and suggest hook-ups and manage to put together a working system.
