Does this connect to the factory wiring harness?

Yes. The LED module is pre-wired to connect at the factory upper grille harness location. No standalone power source or relay needed.

Will I need to remove anything to install this?

You'll need to disconnect the factory grille. Once that's out, this assembly bolts directly into the same mounting points—no drilling, cutting, or bracket modification.

Can I paint or refinish this grille?

The honeycomb mesh is not designed for paint. If color matching is needed, test-fit the grille first to confirm it works with your existing bumper and lighting setup before committing to any finish work.
