！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-0329: 2011-2016 6.6L GM Chevy Duramax LML Tuner Harness Plug Kit,provided for your reference during installation.
This kit is specifically designed for 2011-2016 6.6L GM Chevy Duramax LML 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 | EGR Main Connector | Top of the engine, near the EGR cooler assembly. | Connects to the large main harness that previously controlled EGR functions. |
2 | EGR Actuator Plug | Engine bay, on the EGR valve/cooler bypass. | Seals the secondary actuator control harness for the EGR system. |
3 | Front NOx Sensor | Exhaust downpipe, near the back of the turbo. | Seals the harness connector for the upstream (front) NOx sensor. |
4 | DEF Injector (Doser) | Exhaust pipe, usually located before the SCR catalyst. | Plugs into the harness that previously powered the urea dosing valve. |
5 | Rear NOx Sensor | Exhaust pipe, located in the tailpipe section. | Seals the harness connector for the downstream (rear) NOx sensor. |
6 | EGT Main Interface | Junction of the main exhaust sensor wiring loom. | Protects the wide-format interface connector for grouped EGT sensors. |
7, 8, 9 | EGT / Temp Sensors | Distributed at multiple points along the exhaust piping. | Plugs into individual small-form temperature sensor harness connectors. |
10, 11 | Auxiliary Sensor Plugs | Located in the engine bay or near the sensor rails. | Seals auxiliary temperature or bypass connectors related to the tuner setup. |
12, 13 | DPF Pressure Sensors | Under the vehicle, near the original DPF filter area. | Used to seal the harness connectors for the pressure differential sensors. |
14 | Vent Line Cap | Open vacuum or vent lines (EGR or Tank vents). | Insert into the open end of rubber hoses to prevent dust and debris entry. |
