DESCRIPTION
Product Overview
- After performing race or off-road modifications on 2019+ Ram 6.7L Cummins trucks, unplugged factory sensor plugs and harness leads are left directly exposed to under-hood heat, pressure washing, and road debris. Over time, moisture, road salt, and mud infiltrate these open terminals—causing pin oxidation, terminal pin green-crust corrosion, and shorts that threaten your vehicle's CAN-bus network and body wiring harness.
- Purpose-built for clean, reliable off-road conversions, this Harness Plug Kit includes custom-molded, weather-sealed dust caps designed to click securely into open factory connections. By locking out environmental contaminants, it protects raw electrical terminals against degradation, prevents false signal feedback, and delivers a clean, professional finish under the hood and chassis.
Key Features
- Seals unused factory connectors with weather-tight rubber gaskets that lock out moisture, mud, and road salt
- Manufactured from automotive-grade, heat-resistant polymer designed to survive repeated under-hood thermal cycling
- Uses factory-style locking tabs that click securely into place and won’t back out from engine vibration or off-road pounding
- Installs completely tool-free — plug and play, no wire cutting, no soldering, no tape required
- Delivers a clean, professional engine bay appearance instead of dangling loose wires and taped-up connectors
FAQ
Q: Do these plugs clear check engine lights or delete sensor codes?
A: No. These are strictly protective caps for the physical connectors. They don’t interface with the ECU, modify sensor readings, or clear diagnostic codes. They simply keep connector pins clean and corrosion-free.
Q: Can these handle the heat near the exhaust and turbo?
A: Yes. The polymer material is rated for high-temperature engine bay environments, including areas near the exhaust manifold and turbocharger where radiant heat is most intense.
Q: Why not just cut off the connectors I’m not using?
A: Cutting into the factory wiring harness is permanent and makes it extremely difficult to reverse modifications later — especially if you sell the truck or need dealer service. These plugs give you the same protection with zero permanent alteration.
Q: Does this kit work with the Seguler DPF and EGR delete packages?
A: Yes. It’s the ideal finishing touch after installing a 4"/5" DPF & EGR Delete Kit. Once your emissions hardware is removed, this plug kit seals every leftover connector properly.
