GM 30 pin Truck Harness Dust Cap
Overview
Overview
Did you remove the tailgate on your 2019-2026 GM truck? Use this dust cap to protect the 30 pin connector for the tailgate harness, under the truck, from weather while the tailgate is unplugged!
Simply fill the open holes on this dust cap with silicone to seal the connector. Let dry and slide the cap over the open 30 pin connector on the truck side and press the latch down to lock.
