No, the wiring is not in place, but it can be done in just a matter of a few hours, a few swear words, and a little elbow grease. Here is a link where I learned how to do it. I have just completed setting it up and it works great. HOWEVER: When running the wires like it says, DONT take out the front seat or the radio, it isn't necessary.
