Do the LED DRLs require additional wiring or a custom harness?

Wiring configuration isn't specified in the product data — you'll need to confirm with your vehicle's OEM electrical layout or contact a Ford electrical specialist before installation to avoid cutting into factory circuits.

Will this grille fit if I've already modified my front bumper?

This grille mounts at factory mounting points on your stock bumper opening. If your bumper has been heavily modified or replaced, test-fit the grille before committing to final installation.

Does this need paint or primer before I bolt it on?

The grille arrives ready to install as-is. If you want a custom finish or color match, that's a separate project — the assembly itself doesn't require prep work to mount.
