Do these headlights need any wiring modifications to work?

These mount at factory connection points and accept standard bulb sockets. Confirm your vehicle's wiring diagram before install to ensure compatibility with any auxiliary functions like auto-leveling or washers.

Will the chrome housing stay polished, or does it need protective coating?

Chrome resists tarnish in most conditions. If you live in a coastal or high-salt environment, occasional cleaning with a microfiber cloth keeps the finish bright. No sealant required, but avoid harsh chemicals.
