Will this connect to my existing wiring harness?

Yes, designed for direct OEM electrical integration. Power and ground connect to factory points — confirm connector type matches your vehicle's harness before final installation.

What prep is needed before painting?

Wash with soap and water, then light scuff with fine-grit sandpaper to help paint adhesion. Mask off the mirror glass and any connector areas. Use standard automotive primer and paint for best results.

Do I need special tools to install this?

Standard screwdriver and wrench set handle removal and installation. Work from inside the door panel to access mounting bolts at factory points. Expect 30–45 minutes for experienced DIY install.
