Will this plug straight into my factory wiring harness?

Yes — this mirror uses OEM electrical connectors, so it ties directly into your existing cabin switches and heated mirror circuit. No rewiring needed.

Does the heater work independently from my windshield defogger?

It does. The heated mirror element operates on a separate circuit, so you can run heat to the mirror alone or together with your front and rear defogging systems depending on your vehicle's climate controls.

What condition is this mirror in?

Condition details are not specified in the product data — reach out to confirm whether this is new OEM, used genuine, or refurbished before ordering.
