FAST Wiring Harness F.I. 4&7 Swap - 301201

FAST XFI Fuel Injector Harnesses connect the XFI ECU to the fuel injectors. These harnesses are designed to accommodate most common V8 engines from the Chevrolet Small Block to GM LS Series, Ford Small and Big Blocks as well as Windsor, Modular, FE configurations. FAST also has taken the initiative to help out customers with less common applications such as Buick V6, Modern Chrysler and even 4 cylinder applications. And, while we may not have a custom tailored injector harness that fits your needs, all of our harnesses can be re-pinned for custom firing orders and reterminated to accommodate different injector connectors.

Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth.

When it comes to old cars or engine swaps, you may find yourself needing a new wiring harness. Sometimes your wiring harness gets old and faulty, especially on classic cars. Other times, your may need a new wiring harness with the proper adapters if your are performing an engine swap on your vehicle.
