The Fan & Fuel Pump Wiring Harness Kit from FAST Electronics is purpose-built for builders and tuners integrating F.A.S.T XFi and XFI 2.0 engine control systems into custom, street, and performance vehicles. This universal harness eliminates the guesswork from electrical integration, providing a complete solution for connecting auxiliary cooling and fuel delivery circuits to modern standalone ECU platforms. Whether you're converting a carbureted classic, installing a new control system on a restomod, or upgrading an existing EFI setup, this harness simplifies the critical wiring backbone that keeps your cooling fan and fuel pump functioning reliably.
This wiring harness is engineered with precision connectors and properly gauge conductors designed to handle the power demands of electric cooling fans and fuel pump motors without voltage drop or thermal stress. FAST Electronics manufactures these harnesses to OEM standards, ensuring each connection is crimped and terminated for durability in high-vibration engine bays. The universal design accommodates various fan relay configurations and fuel pump control strategies, reducing the need for custom splicing or adapter workarounds. Pre-assembled construction saves installation time while maintaining professional-grade electrical integrity critical for EFI reliability.
Installers working with F.A.S.T XFi or XFI 2.0 systems—including engine builders, performance shops, and DIY enthusiasts—benefit from the standardized connector interface and documented pin assignments this harness provides. The kit is compatible with most electric fuel pumps and aftermarket cooling fan motors commonly used in hot rods, drag cars, truck builds, and restomod projects. Its compact package and carefully routed leads minimize routing challenges in cramped engine compartments, allowing faster installation and cleaner final presentation. For anyone serious about standalone EFI integration, this harness represents the foundation of a stable, maintainable electrical system.
