DESCRIPTION

Product Overview

  • When installing aftermarket tuning or performance upgrades on your 6.7L Cummins, unused factory wiring connectors can be exposed to moisture, dirt, road salt, and engine heat. Over time, unprotected plugs may corrode and affect electrical reliability.
  • The Tuner Harness Plug Kit provides durable weatherproof caps and dummy plugs to seal unused engine and exhaust harness connectors after modifications.Designed to protect factory wiring from contaminants while keeping your engine bay clean and organized.

Key Features

  • Heavy-Duty Automotive Plastic: Molded from heat-resistant, high-impact ABS polymer designed to withstand harsh under-hood operating conditions.
  • 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 harness plugs after installing performance upgrades?

A: When factory components are removed or bypassed, some electrical connectors may no longer be used. Installing protective plugs helps keep those connectors sealed and prevents long-term exposure to harsh engine bay conditions.

Q: Do these plugs clear Check Engine Lights on their own?

A: No. These are physical protective weather caps. They do not contain electrical resistors or logic circuits to bypass ECM codes. You must have an aftermarket tuner installed to turn off diagnostic trouble codes.

Q: Can I use this with EGR/DPF delete modifications?

A: Yes, In fact, this kit is specifically designed for vehicles undergoing EGR and DPF delete. When removing factory emissions components, these plugs seal and shield the exposed, disconnected wiring connectors to keep them clean, dry, and protected against corrosion and short circuits.

Q: Do I need to install these before tuning my truck?

A: No. These plugs are a protective accessory and can be installed before or after tuning. They are designed to protect unused connectors once factory components are no longer connected.
