Heated and non heated side mirrors same wiring?

I need to replace the drivers side mirror assembly on my 2007 Impala. I'm pretty sure I don't have heated mirrors now, but can I replace the existing with a heated mirror? Is the wiring the same?

Thanks in advance!

I would tend to think no......the new mirror would have the harness on it, but I don't think you would have anything to plug it into....

But the existing mirror is power adjusted, so there is wiring.
