[More Info]
Similar to the changes with the cam and crank sensors, the Drive-By-Wire throttle pedal connector was changed in 2008 on cars while the trucks changed in the 2007 models. Interestingly, the throttle body connector is consistent on all engines. The early pedals use a larger connector. View the image gallery to see both types.
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
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.
