The Cab Wring Harness Seal Plug closes unused or open cavities in cab wiring and harness pass-through areas to prevent unwanted entry of external elements. The plug blocks dust, moisture, and airflow from entering enclosed cab spaces, reducing exposure of nearby wiring and components. It also minimizes noise transfer through open cavities and supports a cleaner internal environment. It closes unused access points, the plug contributes to organized harness routing, and reduces the risk of contamination-related interruptions.Attributes:• Reduces exposure of nearby wiring to external contaminants.• Improves cabin comfort by limiting external air movement.• Creates a sealed closure for unused wiring pass-through locations.• Provided with a contact size of 20.Applications: The Cab Wiring Harness Seal Plug is installed in unused wiring or harness cavities within the cab area to close openings and prevent environmental entry while preserving the option for future harness routing.
