Will this bolt straight to the factory mounting location?

Yes. This mounts at the stock brake light points — no drilling or bracket fabrication required. Do a dry fit first to confirm alignment before final fastening.

Do I need to splice into the brake light wiring, or does this use a plug-and-play connector?

Connection type is not specified. Confirm the wire harness match before purchasing — you may need an adapter or harness splice depending on your truck's electrical connector style.

Is this legal for street use?

This is a LED brake light assembly designed as a direct replacement. Verify your state's regulations on aftermarket brake lights before installation — some regions have specific DOT or brightness requirements.
