I'm looking for some info regarding 07 FX4 mirrors, it looks like I will be replacing my passenger's side mirror (wasn't paying attention, crunched it backing into the garage -ouch). I currently have power adjusting mirrors without heat and the small turn signal, an was thinking to upgrade to heated with the turn signal. Is this possible? I was looking at the Ford web site and it appears that the FX4 Lux package offers these heated w/ turn signal as an option, so getting the mirrors would not be a problem, but getting them to work might be...was wondering if anyone knows is the base wiring is there on the non-lux package and the new mirrors would be a simple plug & go install or am I looking at wiring and all that fun stuff too? Are there any aftermarket options out there?

Thanks, I appreciate the help.
