Description

The Holley Gen III HEMI Drive-By-Wire Harness - Early Pedal (558-417) is an EFI wiring harness designed for early Gen III HEMI engines with the larger TYCO/AMP connector (typically 2003-2007 cars and 2003-2006 trucks). It allows for control of fuel and spark, making it suitable for power upgrades and engine swaps. The harness is compatible with power adders like nitrous, superchargers, or turbos, and supports methanol and water injection. It features TXL grade copper wiring, OEM grade connectors, and a split-loom braid for protection. This harness is for Dominator EFI systems only and is pre-calibrated for the 0459 1847 factory drive-by-wire throttle body. It does not support HEMI's Variable Valve Timing (VVT) or Multi-Displacement System (MDS).
