Dominator EFI Kit - Ford

The Holley Dominator EFI Kit for Ford is a complete engine control system designed for carbureted or speed-density fuel-injected engine conversions on Ford applications. This kit combines Holley's proven Dominator ECU with a dedicated wiring harness and supporting components, providing the core architecture needed to transition from carburetor tuning to fully programmable electronic fuel injection management. The system addresses the critical control layer required for modern drivability, fuel economy optimization, and emissions compliance on classic or modified Ford engines.

The kit includes the Dominator engine control module (ECU) paired with a manufacturer-specific wiring harness sized to match Ford fuel system, ignition, and sensor architecture. The harness is pre-configured to eliminate custom splicing and reduces installation time compared to universal harness kits. At 15.23 lbs, the complete assembly is compact and mounts cleanly in the engine bay. The modular design allows independent component replacement if needed, and the ECU's tuning capability accommodates varying displacement, cam timing, and induction setups typical in Ford street rod, restomod, and performance upgrade applications.

This system is intended for experienced engine builders and shops converting Ford engines to EFI or upgrading existing fuel injection control. Buyers should verify their specific Ford engine platform, model year, and fuel system configuration against Holley's application guide before purchase, as harness compatibility is year and engine-family specific. The Dominator EFI Kit for Ford is the foundational control package for carb-to-injection conversions and tuning-focused Ford engine projects where precision fuel and ignition management is the priority.
