Does this mirror bolt directly to my door?

Yes. Factory mounting points on both the housing and bracket align with OEM door attachment holes—no drilling or modification required.

Can I paint this white finish?

Absolutely. The paintable white base is designed to accept color-matched finish. Light surface cleaning before paint application is standard practice.

Do I need to extend any wiring harness to plug this in?

That depends on your current mirror wiring setup and where the door connector sits. Test-fit the assembly first to confirm distance before running new wire or using extension harnesses.
