A popular add-on for the 6.7L Cummins just got easier to install.

Our Fuel Rail Pressure Gauge Wiring Harness for 2013-2018 Ram 2500 & 3500 trucks is now available, and it delivers faster installs, cleaner connections, and more reliable readings without ever touching factory wiring.

Before, installing a Fuel Rail Pressure Gauge meant digging into the OEM harness, splicing wires and hoping every connection was secure. We redesigned that experience with an effortless Plug and Play connection made specifically for 24 Valve 6.7 Cummins diesel engines. The result is a quicker, more secure install that gets you on the road faster and with no hassles.

This 6.7 Cummins wiring harness connects directly to the fuel rail pressure sensor using a simple inline adapter. Just unplug the factory connector, snap our pigtail wiring kit in place, and tie in the green and black signal wires from the gauge. No cutting, crimping or guesswork required. With 12 inches of harness length and 19 inches of sensor and ground leads, the install has flexibility to route wiring cleanly through the engine bay.

Designed exclusively for 4 Pin OEM sensors, this 6.7 Cummins wiring harness delivers accurate and consistent readings from the common rail system so drivers can stay aware of fuel system performance at all times. If your towing, daily driving or tuning, monitoring rail pressure protects your injectors, pump and overall diesel health.

Plug in. Monitor clearly. Achieve optimal performance for your Ram truck.
