Do these mirrors mount at factory attachment points?

Yes. These are designed to use existing factory mounting holes and electrical connectors — no drilling or custom brackets needed.

Will the heated mirrors stay stable at highway speeds?

Factory-style construction holds solid at speed. If you notice vibration after install, check that all mounting bolts are fully tightened at the door panel.

How do I wire the heating and power functions?

The mirrors tap into your vehicle's existing power and ground lines at the door. Refer to your vehicle's service manual for the correct circuit locations and wire gauges — do not splice directly without confirming amperage specs.
