    Install a GEN III HEMI in Your Hot Rod!

    Mopar enthusiasts are in a league of their own when it comes to brand loyalty. This is especially true to the lineage of the HEMI engine. Holley is excited to offer a complete line of direct-fit wiring harnesses for the GEN III HEMI platform to run a Holley EFI system. This is a huge benefit for Mopar fans as they will now be able to completely tune, program and control the fuel parameters and ignition aspects through the advanced capabilities of a Holley EFI system rather than the limited controls of the factory ECU. Plus, Holley EFI provides additional performance settings for boost control, nitrous configurations, data logging, water/methanol calibration & more. To make installation of a Holley EFI system as easy as possible on late model HEMIs, Holley has developed a line of harnesses that will provide a direct plug-in installation to factory sensors and injectors.

    The late model HEMI has been available since 2003 and is available in several configurations including a 5.7L, 6.1L and 6.4L. Fortunately, the electronics and location of sensors and components are very similar throughout the span of production with only a couple variables in connections. To provide the easiest installation possible, there are several Holley EFI harnesses to compensate for these connector changes. All of the changes are easy to identify visually and we have supplied images of each connector. To determine ECU - Factory HEMI applications all utilized a drive-by-wire throttle body/pedal. If you are retaining the drive-by-wire and its associated advantages, you must run a Dominator ECU. Cable throttle body applications can utilize the HP ECU. A Dominator ECU may be required if the input and outputs used exceed those available on the HP ECU.
