FAQ
WILL THIS WORK ON 2004.5–2005 TRUCKS?No—this integrated harness style is for 2006+ applications. Use 2006–2007 for 5.9L and 2007.5+ for 6.7L.
IS THIS A GENUINE CUMMINS PART?Yes—OE Cummins 5367847 (a.k.a. Integrated Wiring Gasket).
WHAT ENGINES DOES IT COVER OUTSIDE OF RAM?Listed for ISB/QSB 5.9/6.7 industrial variants as an integrated wiring gasket; always confirm by ESN.
DO I NEED ANYTHING ELSE TO INSTALL?Typically just basic hand tools and torque specs. Consider a new rocker box gasket (3963379) if disturbed.
WHY REPLACE VS. REUSE?Heat cycles harden the gasket and degrade wiring insulation/connectors, causing intermittent injector faults.
