Gen III HEMI Main Harness - Late Crank & Cam Sensors

Gen III HEMI Main Harness, For Late Crank & Cam Sensors, for Dominator EFI, Requires DBW Throttle Body Harness. This harness DOES NOT have IAC / TPS connectors.

PART# 558-107

Not Available Online

You MUST use a Chrysler 514-9230-AA crank sensor. This sensor MUST be used when utilizing a 60-2 Ignition Strategy. This sensor is commonly found on 2009-12 Chrysler/Dodge/Jeep applications. 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.

Overview

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.

Features:

  • Take control of your Gen III HEMI with Holley EFI by controlling fuel and spark. Great for power upgrades and engine swaps.
  • Capable of tuning with power adders such as nitrous, superchargers or turbos and compatible with methanol and water injection
  • Harnesses are available to connect to a Gen III HEMI engine for the most advanced fuel and timing controls available
  • Each Harness is designed in fit and function specifically for the Gen III HEMI engine platform
  • All wiring is TXL grade copper wiring with minimal weight, high temp sleeve in a small diameter
  • Factory style terminations provide a strong, secure connection
  • Connectors are OEM grade for a correct, positive fit
  • Each harness is routed through a split-loom braid for protection and great looks
