Will this plug directly into my factory wiring?

Yes. The connectors are pre-wired to match OEM harness layout—no splicing or adapter needed. Plug it in and both power and heating will function immediately.

Do I need to remove the door panel to install this?

You'll need access behind the mirror. Most installs require removing the interior door panel to disconnect the old mirror and route the wiring properly. Refer to your service manual for exact panel removal steps and any fastener torque specs.

Can I return this if it doesn't fit or work?

Contact ModSupply directly with photos and details of the issue—we handle returns and replacements case by case. Keep your receipt and packaging in case a swap is needed.
