Will this plug directly into my wiring harness?

Yes — this is factory OEM equipment, so the connector matches your vehicle's existing electrical system. No adapters or rewiring needed.

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

You'll need to unbolt the driver's side mirror and disconnect the power harness from your old unit. Installation is straightforward if you're comfortable with basic hand tools — reverse the steps to lock this one in place.

Does the heating element come preset, or do I need to configure it?

The heating grid is pre-wired and ready to go. Once installed and connected, activate it through your vehicle's climate or mirror control panel — no calibration required.
