DESCRIPTION
Product Overview
- When performing off-road delete tuning on a 2014–2019 Ram 1500 3.0L EcoDiesel, unplugged DPF, DEF, EGR, and SCR connectors are left exposed to severe moisture, road salt, and dirt, leading to corroded harness pins and costly electrical damage.
- The Ram 1500 3.0L EcoDiesel Tuner Harness Plug Set provides a direct solution. These heavy-duty, Weatherpack blind plugs snap directly into your disconnected factory harness ends to create a 100% weatherproof seal, preserving your truck's original wiring for clean, long-term reliability.
Key Features
- High-Temp Polymeric Material: Molded from automotive-grade, heat-resistant polymer designed to withstand severe under-hood and exhaust bay heat cycles.
- Watertight Weatherproof Seal: High-grade internal rubber gaskets lock out rain, road salt, mud, and dust to eliminate pin corrosion.
- Vibration-Proof Snap Locks: Engineered with factory-style locking tabs that click securely into place, ensuring they will not vibrate loose on or off-road.
- Non-Destructive Installation: Tool-free, plug-and-play installation—no wire cutting, soldering, or messy electrical tape required. Fully reversible back to stock.
FAQ
Q: What does this Tuner Harness Plug Kit do?
A: When you install a delete tuner or performance exhaust, factory emissions sensors are unplugged. This kit supplies heavy-duty cap plugs that seal those empty wire harness ends, shielding sensitive electrical pins from water, dirt, and road salt corrosion.
Q: Do I still need to tune my truck when using this harness plug kit?
A: Yes. These are physical protective caps only. Unplugging emissions sensors without flashing a dedicated delete tune first will immediately trigger Check Engine Lights(CEL) and force your truck into 5 MPH limp mode.
Q: Will this fit 2019+ New Body Style Ram 1500 EcoDiesel models?
A: No. This set is designed exclusively for 2014–2018 Ram 1500 and 2019 Ram 1500 Classic trucks. 5th Gen (2019+) New Body Style EcoDiesels utilize redesigned electrical connectors that require a different plug configuration.
Q: Where on my truck do these protective plugs connect?
A: They snap directly into the open factory wiring sockets left exposed after removing your emissions hardware: Engine Bay (EGR): Plugs into the EGR valve, position sensor, and cooler solenoid harnesses. Underchassis (Exhaust): Plugs into the DPF pressure sensors, EGT probes, and DOC sensor harnesses.
