Do I need to remove the bumper to install this grille?

No. It bolts directly to factory mounting points on the front fascia. You can swap it without removing the entire bumper cover—just unclip or unbolt the old grille and secure this one in its place.

Are the LED DRLs wired to my factory harness, or do I need an aftermarket module?

The LED module is integrated into the grille assembly. Wiring details and connection method are not specified—test-fit the harness connectors before finalizing installation to confirm compatibility with your vehicle's electrical system.

Can I paint this grille, or does it come finished?

It ships with a hard panel finish ready to install as-is. If you want a custom color match, sand the surface and apply your choice of primer and paint before installation to avoid dust and debris settling into the mesh during the cure.
