Do these bolt straight to the factory mounting points?

Yes. These mount at the existing fog light cutouts in the OEM bumper — no drilling or modification needed. Fastening method isn't specified in the product data, so test-fit before committing to bolts or clips.

Will the switch wire into my existing electrical?

The switch assembly is included, but wiring harness routing and integration with your tC's dash depends on your comfort level with electrical work. This isn't a plug-and-play scenario — you'll need to plan the switch location and run power to the fog light circuits.

Do these need paint or any prep before installation?

The chrome bezels are finished as-is and ready to install. If you're working with the bumper cover, prep and paint that separately to match your exterior color before bolting these in.
