      Description

      Protective Dust Cap. The GM Truck Harness Dust Cap (30-Pin) is designed to shield the tailgate harness connector on GM trucks from weather and debris when the tailgate is removed. It protects the truck's electrical system by sealing the 30-pin connector with silicone-filled holes, preventing damage and contamination while the tailgate is unplugged.

      Construction and Appearance. Made as a factory-style connector cap, this dust cap uses durable, weather-resistant materials and offers IP67-rated waterproof and dustproof protection. A secure latch ensures a reliable seal around the connector to guard against environmental exposure.

      Installation. Installation requires no drilling; simply fill the cap’s open holes with silicone sealant, allow it to dry completely, then slide the cap over the exposed connector and press the latch to secure it firmly in place.

      Application. This dust cap is specifically designed for 2020-2026 Sierra 3500 HD models equipped with the 30-pin tailgate connector, providing precise fitment and dependable protection for this vehicle configuration.
