Will this bolt straight into my truck without drilling or cutting?

Yes. This is a direct replacement for the factory 3rd brake light—no modification to the tailgate or mounting points required.

Does the black housing need to be painted?

It ships ready to install as-is. If you want to match a custom color later, the hard panel surface can be prepped and painted.

What electrical connection does it use?

Mounts to factory wiring harness. Test fitment before final installation to confirm the connector type matches your truck's tailgate setup.
