Will this work with my factory wiring harness?

This unit mounts at factory brake light points. LED assemblies are wired to standard brake light circuits — your existing wiring feeds directly into the new light. No adapter harness needed.

Do I need to remove the entire tailgate panel to install this?

Installation depends on your model year's design. Some units access from inside the cargo area; others may require partial panel removal. Test-fit first to confirm your approach before committing to fasteners.

What happens if the LED fails?

LED failure is rare, but if it occurs, the entire assembly is the serviceable unit. Bulb replacement is not an option — you'll need a replacement light. That's why LED longevity is a real advantage here.
