FAST Injector Harness EV1 289302

This FAST XFI Fuel Injector Harness uses Minitimer/EV1 style connectors, a common choice for many aftermarket fuel injection systems. It's built to link your FAST XFI ECU directly to your fuel injectors, ensuring a clean and reliable signal path. This harness is designed to work with a wide range of V8 engines, including popular Ford Small Block, FE, and Big Block configurations, and can be adapted for custom firing orders if needed.

The harness is constructed to handle the demands of engine bay environments, providing a durable connection between your engine control unit and the injectors. While it's a direct fit for many Ford V8s, FAST also designs these harnesses to be re-pinned and re-terminated for less common applications, offering flexibility for custom builds. This means you can often adapt it to different injector types or firing orders, making it a versatile component for your fuel system setup.

If you're installing a FAST XFI system on a Ford Small Block, FE, or Big Block engine, this harness is a key piece to get your injectors wired up correctly. It's designed for a 1-5-4-2-6-3-7-8 firing order, which is standard for many Ford V8s, ensuring proper injector sequencing.
