CP3X2 Harness 2003-2018 Dodge/Ram 2500/3500 5.9/6.7Cummins Fleece Performance
Unlock full diesel performance with the CP3X2 harness for 2003–2018 Cummins. Control dual CP3 pumps directly from your ECM—no expensive controller required.
Take command of your Cummins dual CP3 setup with the CP3X2 harness, designed for 2003–2018 Dodge/Ram 2500/3500 trucks. This performance-focused harness lets you control both CP3 pumps using just your ECM, eliminating the need for a costly dual pump controller. Perfect for high-horsepower builds and serious diesel enthusiasts, the CP3X2 harness supports advanced tuning and maximum fuel delivery.
For optimal results, start by multiplying the stock FCA current table (D0787) by 1.6–1.7 in your Cummins ECM calibration. Fine-tune using EFI Live to match your truck’s unique setup, solenoid characteristics, and lift pump pressure. Methodical FCA table adjustments ensure you hit your rail pressure targets without overshoot or undershoot, giving you smooth idle and race-ready fueling. This harness is engineered for easy install and reliable control—even with heavily modified or triple pump diesel builds.
