Does this switch bolt straight into the factory dash location?

Yes. The switch mounts at the factory fog light switch opening—no drilling or dash modification required. If your vehicle didn't come with fogs from the factory, you'll need to verify the opening exists before ordering.

Will I need additional wiring harness or relay?

The assembly is designed as a direct plug-and-play set, but the exact wiring path depends on your vehicle's electrical configuration. Have a tech or experienced installer verify your factory wiring supports these units before final connection.

What condition do the bezels arrive in—can I install them straight away?

The smoke bezels come finished and ready to mount. No sanding, priming, or painting necessary before installation.
