A weatherproof connector plug set for Ram Cummins is designed to protect unused factory electrical connectors on 6.7L Cummins-powered Ram trucks. These protective caps are especially useful on modified or off-road trucks where certain factory connectors may no longer be connected to their original components. The plugs help keep moisture, dirt, and debris away from exposed electrical connections.

Protect Cummins Wiring

Unused connectors can be exposed to water, dust, mud, and other contaminants under the hood or underneath the truck. A weatherproof connector plug set for Ram Cummins provides a simple way to seal those connections and reduce the chance of contamination and corrosion.

Shibby Engineering offers year-specific tuner harness plug kits for different 6.7L Cummins generations, including 2007-2009, 2009.5-2012, 2013-2015, 2016-2018, and 2019-2024 applications.

OEM-Style Fit

These plug sets are designed to work with compatible factory-style connectors. Instead of cutting or modifying the wiring, the protective caps snap into the unused harness connectors. This provides a cleaner installation while helping protect the original wiring.

For example, the 2019-2024 Ram 6.7L Cummins tuner harness kit uses factory-style interfaces and weather-resistant housings for unused connectors.

The kits can be particularly useful after intake, turbo, exhaust, or other performance modifications where some factory electrical connections are no longer being used. Certain kits also include plugs for connectors associated with EGR, exhaust, and turbo-related components.
