Do these use the factory mounting hole pattern?

Yes. These mirrors mount directly at the factory attachment points — no modification or drilling needed. Test-fit before final installation to confirm clearance on your specific truck.

Will the mirror glass interfere with a tonneau cover or bed extender?

Depends on your tonneau design and how far the mirrors extend when folded. Measure your extended mirror width and compare it to your tonneau footprint before committing. Most stock setups clear standard bed covers, but custom or oversized tonneau systems vary.

How do I wire the power motors to my truck?

Wiring diagrams are vehicle-specific — reference your truck's service manual or wiring schematic for the correct power and ground circuits. Power mirror switches were standard on most models in this generation, so integration is typically straightforward if your truck originally had them.
