The Holley Terminator X Max MPFI System for Ford with Transmission Control is a comprehensive engine control module and wiring harness kit designed to manage fuel injection and transmission operation across both big block and small block Ford engines. This system delivers precise electronic fuel management and drive-by-wire capability, making it an essential upgrade for Ford engine conversions, restorations, and performance builds that require factory-level drivability without factory harness complexity.
The kit combines Holley's proven multiport fuel injection architecture with integrated transmission control, eliminating the need to source separate systems from different manufacturers. The included wiring harness simplifies installation by consolidating all critical connections into one engineered bundle, reducing diagnostic troubleshooting and installation labor. The drive-by-wire configuration removes cable-operated throttle linkage requirements, enabling cleaner engine bay layouts and more responsive throttle response. This system accepts input from modern fuel and ignition sensors, allowing builders to maintain compatibility with contemporary fuel systems while retaining complete control over injection timing and duration.
Purpose-built for Ford engine swaps, vehicle restorations, and custom engine installations where OEM Ford fuel management systems are unavailable or impractical, the Terminator X Max addresses a specific market gap: serious builders who need transmission and fuel control in a single certified package. The system is particularly valuable in classic car restorations where original Ford fuel systems must be replaced, and in custom builds where engine displacement, cylinder configuration, or installation location prevents use of factory control modules. Weighing 10.51 lbs and sized for engine bay mounting, this system scales efficiently across Ford engine platforms without requiring extensive custom wiring or aftermarket adapter integration.
