Will this plug into my factory wiring harness?

Yes, this is designed as a direct replacement. Existing connectors should mate up without modification — test fit before final installation to confirm alignment.

Do I need to remove the tailgate or interior trim to install this?

Installation details vary depending on your specific vehicle layout. Check your service manual for brake light access procedures before starting.

Will this work with factory brake light switches?

LED units operate on the same voltage as stock brake lights. The factory switch activates the circuit the same way — no rewiring needed.
