As far as I know with the upgrading to the heated mirrors you just have to run the wires to a source, and from my understanding it comes from the rear window defroster. I can't remember exactly. I don't regret putting the mirrors in. I never got to hide the wires sadly, but my brother has my car right now and is working on that.
