Do the LED lights come wired and ready to plug in?

Yes, the DRL elements are pre-wired into the grille assembly. You'll need to connect to your vehicle's electrical harness — refer to your truck's service manual for the proper connection points and relay configuration.

Will this grille fit into my factory opening without cutting or drilling?

This grille is designed for the factory grille opening, but test-fit before final installation. Mounting method is not specified in the product data — you may need brackets or fasteners depending on how your truck's grille frame is configured.

Can I repaint this grille if I want a different color?

The matte black finish can be painted over with proper surface prep. Sand lightly, prime, and apply your color choice — prep and paint products are not included with the grille.
