Elite 2500 + V8 Small/Big Block GM, Ford & Chrysler Terminated Harness Kit Injector Connector: Bosch EV1

The Comprehensive V8 Engine Management Solution

Unlocking the full potential of a classic American V8 requires more than just a carburetor tune; it demands the precision of modern electronic fuel injection. The Elite 2500 + V8 Terminated Harness Kit is a complete engine management package designed specifically for popular GM, Ford, and Chrysler Small Block and Big Block engines. This kit combines the powerful Elite 2500 ECU with a fully terminated, plug-and-play engine harness, eliminating the most daunting aspect of EFI conversion: the wiring. Whether you are running a naturally aspirated cruiser, a nitrous-fed drag car, or a forced-induction monster, this kit provides the logic and the connectivity to manage 8 cylinders with sequential precision.

Engineering the Perfect V8 Retrofit

The heart of this package is the terminated harness. Unlike universal looms that require hours of cutting and crimping, this harness is pre-measured and pre-terminated for the physical layout of a standard V8. It features the industry-standard Bosch EV1 injector connectors, making it compatible with a vast array of high-performance fuel injectors. The harness also includes a fully integrated fuse and relay box, handling power distribution for the ECU, fuel pump, and fans without requiring you to hack into the vehicle’s vintage wiring.

Ideally suited for engines using a Distributor or MSD-style ignition system, the kit includes a distributor/MSD ready ignition harness. However, the Elite 2500 is capable of controlling 8 individual ignition coils (Direct Fire) if the user upgrades to a multi-coil setup using an optional extension harness (sold separately). This flexibility allows the system to grow with your build.

Operational Benefits

The Elite 2500 ECU included in this kit offers advanced features like Drive-By-Wire throttle control, dual-channel knock control (essential for protecting expensive V8 builds), and auto-tuning capabilities that learn the fuel map as you drive. For racers, it includes launch control, nitrous control, and data logging.
