Will this connect to my factory mirror controls?

Yes. This mirror is engineered to integrate with OEM wiring and dash switches — no splicing or adapter harnesses needed. Plug directly into the existing electrical connectors at the door.

Do I need new mounting hardware to install this?

Factory mounting points are preserved. Fasteners and brackets will depend on what condition your door panel is in — test-fit first to confirm what you're working with before ordering separate hardware.

Does the heating element work right out of the box?

The heated glass is factory-assembled and ready to function once electrical connections are live. Activate through your existing rear-window defrost button or climate control switch.
