Will this work with my factory wiring harness?

This unit is engineered to integrate at your vehicle's existing third brake light connector. Have a multimeter handy to confirm power and ground at the mounting location before final installation.

Does the lens need to be cleaned or prepped before installation?

Wipe the back of the housing and the mounting surface on your roof with a clean, dry cloth to remove dust and debris. This ensures solid contact if any adhesive surfaces are involved.

Can I install this myself, or do I need a shop?

Installation is designed for DIY with basic hand tools and a socket set. Disconnect the negative battery terminal first, remove fasteners at the factory brake light location, unplug the old unit, and swap in the new one.
