(As far as I can remember) there are three tabs at the top that you slide in like the stockers and there are two or three screws that screw into the grille from behind it. Don't know the technical names for the pieces, but you have to remove some of the plastic covers and things that are between the fascia and the engine bay. Not too difficult, but I remember cutting small notches into my bumper cover to give the hardware a little better fit.
