DESCRIPTION

Product Overview

• When upgrading your 2009-2012 6.7L Cummins, unplugged factory wiring connectors are exposed to moisture, dirt, and engine heat, leading to corrosion and electrical failures over time.
  
• 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

• Prevents Corrosion & Short Circuits: Locks out moisture, dirt, road grime, and engine heat to protect expensive OEM wiring harnesses.
• Complete Harness Protection: Weatherproofs open wiring harness connectors left disconnected after installing aftermarket performance tunes.
• OEM-Style Snap Locks: Built with factory-grade locking tabs and internal rubber seals for a snug, vibration-resistant fit that won't vibrate loose.

FAQ

Q: Why do I need tuner harness plugs on my 09.5-12 truck?

A: After tuning or removing factory components, some OEM electrical connectors may no longer be used. These protective plugs help seal unused connectors from moisture, dirt, road debris, and corrosion.

Q: Does this base kit include DEF tank plugs or SOTF (Shift-On-The-Fly) switch plugs?

A: No. This base kit includes all required caps for under-hood EGR and under-chassis exhaust sensors. It does not include DEF tank connection caps or SOTF switch wiring plugs.

Q: Are these reusable?

A: Yes. The plugs can be removed and reinstalled if factory components need to be serviced or reconnected in the future.

Q: Do these plugs replace factory connectors?

A: No. These are protective covers only and are installed onto existing factory connectors without cutting or modifying the wiring harness.
