DESCRIPTION

Product Overview

If you are upgrading your exhaust or performing a delete on a 20–23 model, removing the DPF, SCR, and DEF systems leaves critical electrical plugs unplugged beneath your truck.
Leaving these sensitive connections exposed to water, road salt, and mud will short-circuit your vehicle’s Controller Area Network (CAN Bus) and trigger immediate limp mode.
This 4-piece plug-and-play set caps off the open factory harness connectors and loops the communication signals, keeping truck's network running flawlessly and protected from the elements.

Key Features

OEM-Grade Weatherproof Seal: Built with high-temperature automotive-grade plastic and premium rubber seals to guarantee a vibration-proof, waterproof fit.
Shields Redesigned Connectors: Specially molded to fit the updated 20-23 GM plug shapes, blocking out water, road salt, and debris.
Completes the CAN Bus Loop: Pre-wired internal loops keep communication channels active between vital onboard modules, preventing communication fault codes (U-codes).
Plug-and-Play: Requires no wire slicing, cutting, or custom pin-swapping. They snap directly into your truck's factory harness in minutes.

FAQ

Q: What happens if I leave the factory connectors open without this kit?

A: You risk immediate corrosion and CAN Bus failure.Moisture and road grime will bridge the exposed pins inside the open harness. This causes electrical shorts that disrupt communication between your ECM and other vital modules, leading to dashboard error codes and limp mode.

Q: Why does a 2020–2023 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: Are these plugs durable enough to handle harsh winter road salt and off-roading?

A: Yes. Made from heat-stabilized, automotive-grade polymer with internal rubber gaskets, they create a waterproof seal that completely blocks out mud, pressure washers, and corrosive winter road salt.

Q: What is included in this "All-In-One" kit, and why buy it as a bundle?

A: This bundle includes the EGR delete, CCV reroute, DPF delete pipe, 3.5" downpipe, and CAN Bus plugs. Bundling guarantees compatibility, saves money over buying parts separately, and cuts labor costs by letting your mechanic install everything at once.
