So you’re one of the lucky ones…there sitting in your garage or shop is a brand new Mustang Cobra Jet, maybe a COPO Camaro and if your a Mopar guy there it is all nice, new and shiny…your Drag Pack Challenger.

No cutting or trimming is required if the FAST® XFI 2.0™ / XIM™ Super Cobra Jet Engine Harness is installed as directed. This saves 30-40 hours of harness building labor and results in a neat, factory-appearing installation. Every harness is also 100-percent tested.
