Will this mirror mount directly to my factory attachment points?

Yes. This mirror bolts to the existing OE mounting locations on your truck — no holes to drill or brackets to fabricate.

Do I need to splice wires, or does it plug into the door harness?

The mirror comes with connectors and adapters designed to integrate with your factory door wiring. Refer to your truck's service manual for proper terminal identification before connecting.

How do I control the power adjustment and heating?

Both functions are tied to your truck's factory mirror control switch on the door panel — no separate controls needed.
