！Before installation, confirm that：
This product is intended exclusively for off-road competition or off-road use. Prior to installation, you must ensure that the vehicle has been flashed with a compatible tuning program (Tune). During installation, it is imperative to use zip ties to secure the wiring harness in a heat-shielded location, positioned well away from the exhaust system. The user assumes full responsibility for any vehicle damage or legal liabilities resulting from illegal use, failure to apply the necessary tuning program, or improper installation (such as the melting of the wiring harness).
This is the installation process for the ER-0330: 2017-2023 6.6L GM Chevy Duramax L5P Tuner Harness Plug Kit,provided for your reference during installation.
This kit is specifically designed for 2017-2023 6.6L GM Chevy Duramax L5P diesel vehicles. Following the tuning and physical removal of the EGR and DPF systems, numerous unused factory wiring connectors remain within the vehicle's chassis and engine bay.
Elimination of Hazards : Prevents electrical interference caused by exposed connectors, ensuring the stable and reliable operation of the modified system.
Waterproof Sealing : Prevents rain, wash water, or road spray from entering open connectors and causing short circuits.
Corrosion and Dust Protection : Blocks dirt, debris, and road salt from corroding the connector pins, thereby safeguarding sensitive signal circuits.

ID | Name | Location | Installation |
1 - 6 | EGT / NOx Sensor Plugs | Located along the exhaust system from the downpipe to the SCR/DPF sections. | Connect to the engine/chassis harness leads where the Exhaust Gas Temp and NOx sensors were unplugged. |
7 & 10 | DEF Pump & Injector Plugs | Located at the DEF tank assembly and the exhaust decomposition pipe. | Plug into the harness connectors that previously powered the DEF pump and the dosing injector. |
8 | EGR Valve Plug | Located on the top of the engine near the intake manifold and EGR cooler. | Secure this to the large factory harness connector that was removed from the EGR valve motor. |
9 | Main Intake / Throttle Plug | Near the air intake horn or throttle body. | Seals the high-pin count connector for the electronic throttle valve. |
11 | Exhaust Pressure Sensor Plug | Mounted on the frame or engine near the pressure lines. | Inserts into the harness connector for the exhaust backpressure sensor. |
12 | Auxiliary Sensor Plug | Variable location depending on specific L5P year model. | Seals any remaining open auxiliary emissions sensor on the chassis harness. |
