2010 mazda 6 headlight assembly and 2011 assembly fit?
 

Hi, i need to know if headlight assembly for 2011-2013 will fit my 2010? I've heard it will but something about wires? How hard to change a wire? Is there a how to for removing the headlight assembly? Thanks in advance.

Any help on if the headlight assembly from newer 2011 or 2012 model will fit without major alterations? The price difference is crazy. I'm not sure why when they look identical.
