Will this plug into my existing mirror wiring harness?

Yes—this is designed as a direct replacement and uses factory electrical connection points. Your existing dashboard controls for power and heat will work without modification.

Does the mirror glass come installed?

The mirror assembly arrives fully assembled. The glass is mounted and ready to bolt on; no additional glass installation is needed.

What if the mirror doesn't heat or signal after installation?

Check that the wiring harness is fully seated at the connection point and that your vehicle's electrical functions are working. If the assembly itself is defective, returns are available within standard windows—contact support with photos and install details.
