Gen III HEMI Injector Harness with Stock/USCAR style Injectors for HP EFI & Dominator EFI

Part Number: 558-210

An Injector Harness is required and Holley offers two. The harness with USCAR/Stock injector connectors will cover most applications that are using the factory injectors. The other harness is for the Bosch and Holley (or Jetronic/Minitimer) injector connector that is commonly used in aftermarket applications for larger injectors. View the image gallery to see images of both types of injectors.

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. _x000D_ _x000D_ 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. _x000D_ _x000D_ NOTE: Not legal for sale or use on pollution controlled vehicles.
