GEN III HEMI MAIN HARNESS - EARLY CRANK & CAM SENSORS
Gen III HEMI Main Harness, For Early Crank & Cam Sensors, for HP EFI & Dominator EFI
This is the main EFI Harness that connects to all of the necessary factory sensors and related EFI sensors to run a Holley EFI system. There is an Early Gen III as well as a Late Gen III harness. The main difference between the early and late harnesses is within the connector for the crank and cam sensors. These changes were implemented across the truck and passenger car lines around 2007. There is not a firm change-over date. View the image gallery to determine the type of crank and cam sensors you have.

Requires the HEMI injector harness, drive-by-wire harness and coil adapter harness. The HEMI’s Variable Valve Timing is not supported by the Holley EFI systems at this time. You can run an engine that is equipped with VVT, but the cam timing will revert to the mechanical default. The Holley R&D team is working on an accessory harness that will drive the VVT actuator. However, it is not available at this time. The HEMI’s Multi-Displacement System (MDS) was primarily designed for fuel economy purposes and does not need to be connected when switching to a Holley EFI system. NOTE: Not legal for sale or use on pollution controlled vehicles.
