Cryptic Tiltle...I know. I'm working on a custom subwoofer box for my lx450 and am trying to clear as musch space in the qp as possible. My question is, what is holding the "Lexus Trailer Wiring Adapter" box to the inside of the rear Pass quarter panel. It feels like its likely just a blob of adhesive..but I dont want to give it a good pull if its tied to one of the fasteners holding the body cladding on. Anyone out there removed this from the wall?
