6.0L Powerstroke Engine Wiring Harness

Replace a brittle, chafed, or hacked engine harness on a late 6.0 Powerstroke with our main wiring assembly. Atlas 5C3Z-12B637-BA is the replacement engine harness for 2005–2007 Super Duty trucks built after November 4, 2004. It restores the correct connector layout and routing for engine-mounted sensors, the glow-plug control module, and the PCM/FICM interface. This is the main engine harness only — injector harnesses are separate.

Verify the build date on the door-jamb sticker or by VIN. Trucks built before 11/04/2004 use a different harness. Confirm the EBP sensor is on the FICM bracket / driver’s valve cover for this later style. Does not fit 2003–early 2004 trucks or gas engines.
