DESCRIPTION
Product Overview
- Unplugged factory sensor wiring on 2016–2018 6.7L Cummins trucks presents a constant risk to your electrical system after installing tuner software or removing stock hardware. Open connector plugs along the chassis and engine compartment are left vulnerable to rain, mud, road salt, and engine heat—leading to short circuits and expensive harness replacement.
- This Weatherproof Tuner Harness Cap Kit provides an instant, snap-in defense for all unused electrical connections. Featuring durable, precision-molded protective plugs, it seals out moisture and dirt to safeguard sensitive connector pins, protect your truck’s factory wiring, and deliver a clean, streamlined look under the hood.
Key Features
- Shield exposed factory wiring connectors from moisture, road salt, mud, and corrosion with precision-molded weatherproof plugs
- Prevent intermittent short circuits, signal noise, and ghost diagnostic trouble codes by protecting open pin terminals
- Snap securely into OEM connector housings with factory-style locking tabs that won’t vibrate loose under heavy use
- Withstand harsh under-hood temperatures and chemical exposure with heat-resistant, high-impact ABS polymer construction
- Remove and reinstall without tools — connectors stay accessible for future maintenance or a return to factory configuration
FAQ
Q: What is a tuner harness plug kit used for?
A: It seals unused factory wiring connectors that are left exposed after tuning or aftermarket modifications. It protects open connectors from moisture, dirt, road debris, and corrosion that can cause electrical failures over time.
Q: Do I need these if my tuner already disables the factory components?
A: Yes. Tuning may disable the electronic functionality of a component, but the physical connector socket remains exposed to the elements. These plugs provide the physical barrier that software cannot.
Q: Will installing these plugs affect future maintenance or a return to stock?
A: No. The plugs are removable and allow easy access to the original connectors whenever you need to service factory components or revert to the original configuration.
Q: Can these harness plugs handle the heat under the hood?
A: Yes. The plugs are molded from heat-resistant, high-impact ABS polymer specifically engineered to endure sustained engine bay temperatures, vibration, and exposure to oil and road contaminants during both daily driving and heavy-duty use.
