I don't know if you have a "Best Buy" electronics store near you, but I bought an aftermarket Pioneer from them. They not only had the plastic adapter to make the new stereo fit the old hole (it's so perfect, you would think it came from the factory with a Pioneer in it), but they also have a wiring harness that simply plugs into your existing harness in the 1st gen. No more splicing and searching for the right wires. If you continue to have a problem, let me know, the adapter was cheap, and I could get one and mail it to you.
