Will the illumination wire connect to my factory harness?

The visor is pre-wired and designed to plug into the factory connector. Test the connection before final installation to ensure the mirror light powers on properly.

Does this need any prep work before installation?

No prep required. This is a direct replacement — simply unclip the old visor and snap the new one into the existing mounting brackets.

What if the mirror light doesn't work after I install it?

Check the factory connector for corrosion or loose pins and reseat it firmly. If the connector is clean and secure but the light still doesn't function, the factory wiring may need inspection — refer to your vehicle's service manual for circuit diagnostics.
