DESCRIPTION

Product Overview

When perform an exhaust delete or upgrade 17–19 L5P Duramax, removing the factory DPF, SCR, and DEF systems leaves several vital electrical connectors unplugged underneath truck.
These exposed connectors link directly to truck’s sensitive Controller Area Network (CAN Bus). Leaving them open to road grime, water, salt, and mud will cause electrical shorts, communication errors, and throw truck into immediate limp mode.
The CAN Bus Plug Kit is a must-have, plug-and-play solution. It caps off the open factory harness connectors and loops the CAN Bus signals, protecting electrical system and keeping your communication network running flawlessly.

Key Features

OEM-Quality Sealing: Built with premium weather-resistant seals and locking tabs, guaranteeing a tight, vibration-proof, and completely waterproof fit.
Protects Sensitive Electronics: Acts as a heavy-duty shield, preventing water, dust, salt, and mud from entering your truck’s unplugged wiring harness.
Maintains CAN Bus Loop: Pre-wired loop pins complete the circuit, ensuring seamless ECM communication with other modules without throwing fault codes.
Plug-and-Play: No cutting, splicing, or custom wiring required. Simply snap them into your existing factory connectors in place of the removed sensors.

FAQ

Q: Why does an L5P need these plugs after an exhaust upgrade?

A: Removing factory emissions equipment leaves open harness plugs under your truck. This kit caps those ports to keep out water and dirt while completing the CAN Bus circuit for normal module communication.

Q: Will these plugs work on 2020 or newer L5P Duramax models?

A: No. GM redesigned the electrical connectors for 2020+ models, so 2017–2019 plugs will not fit. This 20–23 Can bus plugs features the updated plug profiles and pin configurations required to safely loop your network.

Q: Do I need a custom tune to use these plugs?

A: Yes.While these plugs physically complete the electrical circuits, they are used during emissions equipment modifications. You still need an engine tune to disable the deleted sensor logic in the computer and prevent CELs.

Q: Where exactly under the truck do these four plugs install?

A: Three black plugs cap the connections near the frame rail and transmission area (where the DEF and NOx modules unplugged). The grey plug serves as the terminator, snapping into the main harness connector near the rear chassis.
