As others have said you need to spend some time preparing the hole. I used a dremel and hand sanded for the final finish. The cable is designed to fit into a very thin panel, maybe 1/16-1/8 inch, but that's easily adjusted by trimming the plastic ears that hold it in place. I added this to an internal slide out panel in my Mustang 06 console to allow the Apple Car Play to connect to the secondary radio and it works great.
