Do I need to remove the factory brake light before installing this?

Yes. You'll need basic hand tools to access and remove the OEM third brake light assembly from inside the cargo area. Once removed, the new unit installs at the same mounting points with no drilling or modification required.

Will this work with my factory wiring harness?

The assembly is designed for OEM location mounting. Verify connector compatibility with your vehicle's existing harness before purchase — pin configuration is not specified in the product listing.

Can I paint the smoked lens if I want a different finish?

The lens is not intended for painting. If you need a different color, you'll want to source an alternative housing. Painting may compromise light transmission and durability.
