Will this grille work with my factory LEDs, or do I need separate wiring?

The grille comes LED-equipped, but electrical hookup depends on your truck's current lighting setup. If your truck has factory LED headlights, you may need a harness adapter — check compatibility with your specific year before ordering. If you're running non-LED headlights, you'll need to wire the grille LEDs into your daytime running light circuit or a separate switch.

Does this mount directly at the factory grille opening, or do I need brackets?

It installs at factory mounting points with no brackets or drilling. Remove your old grille, disconnect any wiring from existing lights, and bolt this one in place using the same holes.

What's the finish when it arrives — can I paint it or does it need prep?

The grille arrives ready to install as-is. If you want to match your bumper color or customize the finish, standard automotive prep and paint techniques apply — treat it like any hard plastic grille panel you'd customize.
