DESCRIPTION
Product Overview
- When installing aftermarket tuning or deleting factory emissions hardware on a 2016–2018 6.7L Cummins, multiple underhood and chassis electrical connectors are left unplugged and exposed.
- Leaving open sensor sockets exposed to rain, mud, road salt, and engine heat leads to severe pin corrosion, short circuits, and damaged wiring harnesses.
- The Tuner Harness Plug Kit high-impact plugs lock out moisture and dirt to protect your truck’s electrical system and maintain a clean, professional engine bay and chassis layout.
Key Features

- Eliminates Electrical Interference: Protects exposed pin terminals to prevent short circuits, signal noise, and phantom fault codes.
- Factory-Style Locking Snap Interfaces: Precision-molded tabs align perfectly with original OEM plugs for a snug, vibration-proof seal.
- Complete Harness Protection: Weatherproofs open wiring harness connectors left disconnected after installing aftermarket performance tunes.
FAQ
Q: What is a Tuner Harness Plug Kit used for?
A: This kit seals unused factory wiring connectors after tuning or aftermarket modifications. It helps protect exposed connectors from moisture, dirt, road debris, and corrosion.
Q: Do I need these if my tuner already disables the factory components?
A: Yes. Tuning may disable electronic functions, but unused physical connectors are still exposed to the environment. These plugs provide additional protection for the factory wiring.
Q: Will installing these affect future maintenance?
A: No. The plugs are removable and allow easy access to the original connectors if factory components need to be serviced or reinstalled.
Q: Are these plugs heat resistant for engine bay use?
A: Yes. These harness plugs are designed to withstand typical engine bay conditions, including heat, vibration, and exposure to road contaminants, helping protect unused factory connectors during daily driving and heavy-duty use.
