Will this mirror plug directly into my truck's existing wiring?

These mirrors are designed for factory mounting points, but wiring compatibility depends on your truck's configuration and whether it originally had power mirrors. Test the connector fit before committing.

Do I need to remove the old mirror to install this?

Yes. You'll need to disconnect the power connector and unbolt the existing mirror from the door. The new assembly mounts at the same factory points — no drilling or modification required.

Is there any prep work before I bolt it on?

Inspect the mounting surface for damage or corrosion. Clean the area and ensure all fastener holes align before final installation. If any hardware is damaged or missing, source replacements before assembly.
