The Holley Injector Harness V8 Evenly Spaced USCAR (SKU HLY558-210) is a professional-grade fuel injector adapter harness designed to bridge fuel injection systems across different connector standards. This harness converts USCAR EV6 injector connectors to Bosch Jetronic and Minitimer compatibility, making it essential for engine swap projects, carbureted-to-fuel-injection conversions, and custom fuel system installations where stock connector types don't align with modern fuel delivery components.
Holley's harness accommodates evenly spaced V8 injector configurations, ensuring proper electrical signaling and voltage delivery to each injector without signal degradation or ground loop issues. The adapter design eliminates the need for cutting and splicing OEM wiring, reducing installation time and minimizing potential electrical failures. Weighing 0.75 lbs and measuring 10.75 x 2.3 x 10.75 inches, the harness integrates cleanly into engine bays with minimal footprint. Each unit is sold individually, allowing builders to order multiple harnesses for multi-vehicle projects or as backup components.
This adapter harness is built for engine builders, performance shops, and DIY enthusiasts tackling V8 engine conversions where fuel injection systems from different OEM sources must communicate through a single wiring harness. Common applications include LS swaps into classic vehicles, turbocharged engine integrations, and standalone fuel management system installations. Proper connector matching prevents injector misfiring, fuel delivery inconsistencies, and potential engine damage from electrical incompatibility.
Holley's reputation in fuel system engineering makes this harness a trusted solution for builders who prioritize reliability in high-performance and custom engine applications. The USCAR to Bosch/Minitimer adapter standard is widely recognized across the aftermarket performance and restoration communities as the industry-standard conversion method for multi-source fuel injection integration.
