Will this plug directly into my factory wiring?

Yes. The harness connects straight to your existing center brake light connector — no splicing or rewiring needed.

Do I need to remove my old brake light or can I test-fit first?

Test-fit before removing the original. The factory mounting points align, but confirm clearance and connector orientation match before committing.

Is the lens already sealed, or do I need to apply sealant during installation?

Assembly arrives sealed at the factory. If you remove the light for any reason, apply automotive silicone around the mounting base before reinstalling to prevent water intrusion.
