Do I need any extra hardware to install this mirror?

The mirror mounts at factory rocker points—no drilling or custom brackets required. You'll need basic hand tools and a trim removal tool to access the mounting clips. Check your vehicle's service manual for any torque specs on the mounting bolts.

Will this plug into my existing wiring harness?

This mirror is designed for factory electrical connections on 2017-18 Elantra models. The connector type and wiring configuration are OEM-matched. Test fit the connector before final installation to confirm alignment.

What if the power fold or heating doesn't work when I install it?

Check that all connectors are fully seated and the vehicle battery is in good condition—low voltage can prevent power functions from responding. Verify your door lock switches are functioning, as fold activation ties directly to lock/unlock commands on some models. If both features still don't work after those checks, the mirror assembly itself may need evaluation.
