Does this mirror connect to my factory wiring?

Yes—mounts at OEM electrical points, so no additional harnesses or relays are needed. Plug in and wire per your vehicle's factory schematic.

Can I paint this before or after installation?

Paint before install for cleaner coverage and easier masking. The housing accepts primer and topcoat without prep; final cure time depends on your paint system.

What fasteners do I need to mount it?

Mounting hardware is not included—use the fasteners from your OEM mirror or purchase metric bolts sized to factory attachment points on your vehicle's door frame.
