DESCRIPTION

Product Overview

  • When installing performance upgrades or custom tuning on 2019+ Ram 6.7L Cummins trucks, factory emissions modifications can leave unused electrical connectors exposed to harsh conditions.
  • Moisture, mud, road salt, and engine heat can cause connector corrosion over time, potentially affecting wiring reliability and electrical connections.
  • The Harness Plug Kit provides precision-molded, weather-resistant caps to seal unused factory connectors throughout the truck. It helps protect wiring from contaminants while maintaining a clean, professional OEM-style appearance.

Key Features

  • High-Temp Polymeric Material: Molded from automotive-grade, heat-resistant polymer designed to withstand severe under-hood and exhaust bay heat cycles.
  • Watertight Weatherproof Seal: High-grade internal rubber gaskets lock out rain, road salt, mud, and dust to eliminate pin corrosion.
  • Vibration-Proof Snap Locks: Engineered with factory-style locking tabs that click securely into place, ensuring they will not vibrate loose on or off-road.
  • Non-Destructive Installation: Tool-free, plug-and-play installation—no wire cutting, soldering, or messy electrical tape required. Fully reversible back to stock.

FAQ

Q: What is a Tuner Harness Plug Kit used for?

A: After modifying factory emissions components or installing custom tuning, some OEM connectors may no longer be used. These protective plugs help keep connectors sealed and maintain long-term wiring reliability.

Q: Are these plugs heat resistant?

A: Yes. These plugs are designed for demanding diesel truck environments and help protect unused connectors exposed to engine heat, vibration, moisture, and road debris.

Q: Do these plugs affect ECU operation or tuning?

A: No. These are protective caps only. They do not modify ECU signals, change tuning parameters, or affect engine calibration.

Q: Will these stop check engine lights?

A: No. These plugs do not disable sensors, clear diagnostic codes, or change ECU programming. They only protect unused electrical connectors.

Q: Why not just remove the unused connectors completely?

A: Factory connectors are part of the vehicle’s original wiring harness. Removing them requires permanent wiring modifications and can make future servicing more difficult. These plugs provide a simple, reversible way to protect unused connections.
