Will this work with my factory wiring harness?

This assembly mounts at factory points, but wiring compatibility depends on your specific truck's electrical configuration. You may need an adapter harness or relay module — test-fit and consult your vehicle's wiring diagram before final installation.

Do I need to remove anything to install this?

You'll need to remove the OEM 3rd brake light to access the mounting surface. The new assembly installs at the same location using factory mounting points — no drilling required.

Is there a warranty or return window if it doesn't fit?

Contact support directly with photos of your truck's brake light area and we can confirm fitment before you buy. Returns are handled on a case-by-case basis — reach out before committing.
