FAST offers several main harness options to accommodate most customers' needs. The XFI Main Harness is responsible for connecting your XFI ECU to sensors as well as digital dashes, EGT modules, and various optional accessories. The Main Harness also handles communication between the ECU and ignition devices. Main harnesses are available in TPI, LT-1, LS-1 through 9 (including truck/suv designs), Modern Hemi, Carburetor Conversions and even Rear-Engine Dragsters and Boats.
