Truck-Lite 97002 .180 Receptacle Filler Plug (Dummy Dust Cap for Chassis Ground & ID/License Harnesses)

Protect your vehicle’s unused electrical circuits from devastating moisture and corrosion with the Truck-Lite 97002 .180 Receptacle Filler Plug. When leaving a connector port open or staging an unpopulated terminal on a commercial trailer chassis or identification lamp harness, using a dummy filler plug is the professional way to ensure long-term fleet electrical reliability.

Engineered to act as an airtight, watertight dust cap, this premium filler plug snaps firmly into any standard .180 receptacle. It acts as a physical shield that locks out road salt, grime, mud, and water ingress. By sealing off open ports, the 97002 plug effectively prevents green-wire corrosion from spreading through your main lighting system loops and triggering unexpected signaling failures.

Constructed from rugged, automotive-grade thermoplastic materials built to absorb heavy chassis vibration and survive severe weather extremes, this plug is a mandatory addition to any fleet maintenance bay or repair kit. Keep your electrical configurations clean, organized, and fully insulated with this genuine Truck-Lite harness accessory.
