Will this plug into my factory wiring harness?

Yes. This assembly uses the factory connector — no splicing or aftermarket adapters required. Plug it in and you're done.

Do I need to remove anything from my vehicle to install this?

You'll need to access the mounting points from inside the cargo area or tailgate. The exact procedure depends on your vehicle's interior trim — check your service manual for panel removal steps.

Is the lens sealed against water?

Hard panel construction is designed for durability and weather resistance. For peace of mind, inspect the seal after installation and ensure fasteners are snug.
