Do these mirrors mount at the factory attachment points?

Yes — these are designed as direct replacements using OEM mounting locations. No drilling or frame modification needed.

How do I wire the heated glass and puddle lights?

Mirrors connect to your truck's electrical system via factory harness connections. Refer to your vehicle's service manual for circuit routing and fuse specifications.

Will the mirrors stay stable when folded at highway speeds?

The power fold mechanism is designed for parked storage only — fold them in when the vehicle is stopped. At speed, keep mirrors in the extended position.
