On my 2002, it was in the upper left of the left side entertainment cabinet. In my 2007, it is in the upper right of the same cabinet. I am sure that yours is in that area. A converter box would be hooked up after the booster.
I don't know how your components are mounted. On both of our units, the sound components were held in place with Velcro. The "tube type" TV's were held in with a wood wedge, on top of the TV, that was covered with carpet like material.
