Should be like any front bumper cover swap: the bumper cover itself, the center grille, and lower grille/valance.
The fog light connectors changed in the 2011 to 2012 V6
to GT arrangements: the V6's used an H11 bulb, and the GT's used an H10.
Don't know what the 2013's and up are using in the way of fog light bulbs (since the V6 and GT's share the same front bumper cover now). A quick look in an owners manual would tell us.
This would only be important if you had fog lights in an early V6, and were going to the California
Special 2013 and up front bumper cover style swap and wanted to retain the fog lights. You can slice or buy adaptors (H11 to H10 and vice versa) from Ebay.
