Will this work with my stock wiring harness?

Yes. This is a direct replacement that uses your existing center brake light connector — no rewiring or adapter harnesses needed.

Do I need to remove the old light housing first?

Standard removal applies: unbolt the factory unit from inside the hatch area, disconnect the harness, then bolt the LED assembly in its place using the same mounting points.

Is the smoke tint factory-legal?

The lens is designed to meet DOT visibility standards while providing a tinted appearance — but vehicle codes vary by state. Verify local regulations before installation.
