very complicated process. I have never heard of a harness that would make life that easy but i could be wrong so, the first off, I would say dig a little deeper on the harness you are curious about. I dont show any speaker wire colors in any of my diagrams. One easy way to figure out what the wire colors are is to pop your trunk and look at your plugs at your rear speakers. When looking at your factory amp, they should be the same color. Do you have a multi meter? If you put it on ohms and go by the process of elimination (I know it will be lengthy but it will work) and check two wires at a time until it reads (2 ohms). You will already have the wires for the rear speakers so the only thing left would be for the fronts. Your tweeters may also be ran seperately and may have the same exact color as your front door speakers so, dont be surprised if you find two sets of identical colored wires. Pop the speakers to see which ones make noise with some scrap wires and a 9 volt battery. The harness will have other wires on it as well but they will not be used. If you dont want to do this, you could also just run your own wires but this is a bit tideous as well but honestly, if time was not an issue, that is what I would do.
