Will this mount using the factory holes?

Yes. This mirror bolts directly to the existing factory attachment points on your door — no drilling or custom brackets required.

Do I need to remove the door panel to install this?

No. Access is from the exterior side. Disconnect the wiring harness if your truck has power mirrors, unbolt the old mirror, and bolt the new one in place.

Does this come with any wiring or connectors?

Mirror assembly only — no additional wiring included. If your truck has power-adjustable mirrors, reuse the existing harness from your old mirror.
