Hello - I had purchased a 2016 Pro 4x just a few months ago and am adding a few little things to it to make it "mine". Since I live in Wisconsin I am adding heated mirrors; the vehicle was purchased in Arizona and does not have a heated rear window nor does it have any kind of heating button for a rear window. I don't even know what that switch would look like. I looked at my user's manual and it doesn't picture or comment on any of this. Would very much like to know if the heated mirrors will work without too much rewiring? That's one of projects. Anyway - found this forum and thought it might be a good one to belong so I may benefit from others with the same kind of vehicle. Thank you and have an enjoyable day!
