Does this require any additional wiring beyond what's in the box?

The harness connects directly to the switch and lights included in the kit. Tap into your vehicle's battery and ground per the included instructions—no additional relay or module needed.

Will these mount to the factory fog light holes on my bumper?

Yes, these are designed for factory mounting points on the Super Duty bumper. Test-fit before final fastening to confirm alignment on your specific model year.

Do the lights need to be painted or finished before installation?

The lights ship ready to install. If you're painting your bumper or want a custom finish, remove the lights first and reinstall after paint work is complete.
