Will this plug directly into my truck's wiring, or do I need an adapter?

Factory connector matches OEM harness—no adapter needed if you're replacing an existing heated mirror. If your truck came with manual mirrors, you'll need to verify connector compatibility before installation.

Does the heating element work independently, or does it activate with the rear defrost?

Heating activation depends on your truck's electrical setup. On most OEM systems, mirror heat ties to the rear defrost button, but verify your vehicle's control layout before installation.

What's your return policy if the heater doesn't function after install?

Inspect all wiring connections and test power delivery at the mirror connector before requesting a return. Most heating failures are wiring-related, not component failures. Contact support with photos of your connection for troubleshooting before initiating a return.
