This comprehensive, custom-fit engine wiring harness is designed to integrate with the factory vehicle harness, switch panel and other components of Cobra Jet engines. It is the same system used by top NHRA and NMCA Stock Eliminator and Super Stock racers such as Anthony Bongiovanni, Gary Richard, Jeff Roell, P.B. Candies, Randy Eakins, Roy Hill, Don Bowles, Susan McClenaghan and Chuck Watson. The wiring harness offers several mounting options for the ECU and ignition module. It also features heavy-duty heat and abrasion-resistant sheathing with heat-shrink-sealed ends on the underhood portion. There is double EMI shielding on critical harness leads, plus durable braided nylon sheathing on the under-dash portion of the harness. It is compatible with Ford’s 5.4 Modular and 5.0 Coyote engines, either naturally aspirated or supercharged. The harness includes a detailed vehicle-specific installation guide for integrating the engine harness to the factory switch panel, factory Launch Control/2-Step function and factory gauges. This allows for simple data-logging of factory-installed sensors like fuel pressure, oil pressure and brake pressure into the XFI 2.0TM ECU. No cutting or trimming is required if the FAST® XFI 2.0TM / XIMTM Super Cobra Jet Engine Harness is installed as directed. This saves 30-40 hoursbuilding labor and results in a neat, factory-appearing installation. Every harness is also 100-percent tested.
