Good To Know
Q: Can I install this without removing the tail light housing? A: Yes, the harness connects behind the tail light lens, but removing the housing makes access easier and prevents wire strain.
Q: Does this work with a trailer wiring kit? A: It replaces the factory tail light wiring; a separate trailer harness is needed if you are adding towing circuits.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
