Good To Know

Q: Is this harness the same for a Z71 or LT trim? A: The part number listed is for the Base trim, but the main body wiring is often shared across trims; check your connector shape against your old harness.

Q: Can I install this without cutting any wires? A: Yes, the harness is designed to plug directly into the existing connectors without splicing, provided your matching connectors in the truck bed are intact.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
