just get a wire harness for your car, they should sell them at any car audio store, makes things a lot easier, all the wires match up to the color for most of them, makes an hour into about 20 minutes at most.
Ok, I'm gonna step in here and just say, don't do it. Take it to a store, have one of their senior guys do it, DO NOT try to do it yourself. The wiring for the stereo is just ungodly. Let them do it. I promise you will be happier with it.
