Will this lens work with my existing mirror housing?

Yes. This lens mounts directly to factory mirror housings without modification. Alignment is built to OEM spec, so it seats flush in the existing frame.

Does the heating element plug into my current wiring harness?

The heating connector is factory-style and designed for direct connection to your vehicle's existing heated mirror circuit. No additional relay or switch is needed if your mirror already has power.

What if the lens arrives damaged or doesn't heat up?

Test the lens against your mirror housing before permanent installation. If the heating element fails after install, contact support with photos of the connector and wiring confirmation for warranty evaluation.
