！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-0327: 2016-2018 6.7L Ram Cummins Tuner Harness Plug Kit,provided for your reference during installation.
This kit is specifically designed for 2016-2018 6.7L Ram Cummins 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 - 5 | EGT/NOx Sensor Plugs | Along the exhaust frame rail | Connect to the 5 small factory harness leads where the Temperature (EGT) and NOx sensors were disconnected. |
6 | DEF Pump Main Plug | Above the rear axle / DEF tank | The largest square plug; connects to the primary main power harness for the DEF pump assembly. |
7 | Large DEF Tank Connector | Side of the DEF tank | Wide flat-style cap; fits the larger secondary sensor connector on the DEF tank. |
8 | Pressure Sensor (Large) | Mid-chassis / Passenger side | Longer flat-faced plug; protects the primary SCR/DPF pressure sensor harness. |
9 | Pressure Sensor (Small) | Mid-chassis/Underbody | Compact rounded-rectangular plug; fits the secondary or auxiliary pressure sensor leads. |
10 | DEF Injector Plug | Exhaust pipe mid-section | Medium-width flat cap; specifically sized for the DEF injector (doser) harness connector. |
11 | Vent Tube Plug | DEF Tank area | Small white plastic barb; insert into the open DEF vent line to block dust and debris. |
12 | Throttle/Sub-Harness Plug | Engine bay or chassis rail | Multi-pin plug with red locking tab; protects the 2016+ specific throttle or auxiliary sub-harness. |
13 | 8-Pin Main Distribution Cap | Main chassis harness junction | Large 8-hole cap; secures the high-pin count junction connector on the frame. |
14 | Gray Auxiliary Sensor Plug | Underbody emissions harness | Gray 4-hole oval plug; used for specific trim levels or variations in the NOx control module. |
15 | EGR Actuator Plug | Top of the engine (EGR area) | Round-base connector; protects the EGR motor/actuator harness after the EGR system is bypassed. |
