Product Description

The FAST 301104 is the main wiring harness for FAST XFI EFI systems installed on Chrysler Gen III HEMI engines -- the 5.7L (2003-present), 6.1L (2005-2010), and 6.4L (2011-present). It connects the XFI ECU to the engine's OEM MAP sensor, throttle position sensor, coolant temp sensor, and air temp sensor using Mopar-style connectors, and also handles communication between the ECU and ignition devices, digital dashes, EGT modules, and optional accessories.

All wires are clearly labeled and every end comes pre-terminated with Weather Pack connectors -- the same environmentally sealed connectors used by OEM automotive, construction, and farm equipment manufacturers for their ability to withstand extreme temperatures, moisture, and engine bay chemicals. For use with FAST XFI EFI systems only -- not a factory harness replacement. Does not include sensors. Race and off-road use only -- not California emissions legal for street use.
