Do the LED lights come pre-wired, or do I need to run new wiring?

They're pre-wired into the assembly. You'll integrate into your factory DRL circuit or run a clean tap to your battery and ground — no custom harness fabrication.

Will this grille fit if my factory grille is damaged?

This mounts into the existing grille opening using factory attachment points. If your bumper or grille frame is bent or cracked, have those addressed first — the mesh grille itself won't reinforce a compromised frame.

Does it need paint before install?

The grille comes ready to bolt in as-is. If you want it color-matched to your bumper or trim, prep with a degreaser, sand lightly, and paint with automotive trim paint before mounting.
