Will this cover my fog light cutouts, or do I need to make new ones?

This bumper ships with the fog light openings pre-cut to factory size. No modification needed if your vehicle originally had fog lights. If yours didn't come equipped, you'll need to cut the holes yourself during installation.

Does this bumper have pre-drilled holes for sensor wiring or parking sensor cutouts?

The cover does not include pre-drilled sensor holes. If your vehicle has parking sensors on the original bumper, you'll need to carefully drill or cut access points during the install to route wiring through.

Can I install this before painting, or should I paint first?

You can bolt it on unpainted to verify fitment and make any final adjustments, then remove it for painting and primer application. Most builders prefer to paint off the vehicle for a cleaner finish and easier masking around mounting points.
