Good To Know
Q: Can this harness be used on a 1500 non-HD model? A: This harness is specifically designed for the 1500HD, 2500HD, and 3500 series. Confirm your truck's series and model year to ensure correct fitment, as the HD and non-HD models may use different connectors.
Q: Does this harness include the bulb socket? A: No, this is the wiring harness only, which connects to the tail light assembly and the vehicle's main harness. It does not include the tail light housing or bulb sockets.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
