I have an '05 Mazda 3 hatch, 5 speed, and it is lacking cruise and power mirrors. Cruise isn't an issue to have installed, but I am curious about the power mirrors. Has anyone put in stock power mirrors on a 3 before on a car that did not have it? Could it be done? Does the wiring harness include the connections and wiring for the mirrors?

3's that have power mirrors have tweeters in the top door panel. Would I also be able to hook up a set and use them? I am planning on swapping out the stock single CD deck for the stock MP3 six changer. What about air temp. sensors for the radio?

Thanks for your help.
