Do I need to prep this before painting?

Light scuff with fine grit sandpaper and a clean wipe-down will help paint adhesion. Primer is recommended but check your paint system's requirements—different paints have different surface prep needs.

What hardware do I need to install this?

The mirror bolts to factory mounting points on your door. You'll need basic hand tools and the fasteners that came with your vehicle originally—grab those if you have them, or reference your service manual for the correct spec.

Does the power function plug straight into my door harness?

Yes, it's designed for OEM electrical integration. The connector should match your factory harness—test the fit before final install to confirm alignment with your door wiring.
