Hi, unfortunately there is not an assembly available for the 2010-on, (there was for the 2005-2009, as well as the mirrors with the turn signal lights), so you have to modify the tailights. Here's some kind of scheme :
RETRONEBBIA = Rear fog lights (mandatory), you have also to connect it in a switch in the cabin.
POSIZIONE = Markers
INDICATORI DI DIREZIONE = Turn signals (they has to be added and must be yellow)
Again, for being more sure and made a proper work contact Luca or the other company. If not done in a certain mode, adapting the lights can overload lights controllers and damage the vehicle electronics seriously. We've got many stang over here with blown up electronics not able to even start engine because of incompetent \ unskilled electricians...
