Do I need to connect this to my existing power mirror wiring?

Yes. This mirror is designed to work with your factory electrical harness. Alignment with your existing door panel connectors at the mounting points will allow the power function to operate through your vehicle's door switch.

Will this mirror require any painting or prep before installation?

The mirror arrives ready to install. If your vehicle has been repainted or the trim color differs, you may want to color-match the housing before fitting.

What if the mirror doesn't align perfectly with my door after installation?

Minor adjustment is possible at the factory mounting points once the mirror is secured. If fitment gaps appear larger than expected, verify that all fasteners are tight and the mounting brackets are properly seated before considering further modifications.
