The PRO550/600 FTSPARK-8 Harness for Chevy/Chrysler is a precision ignition wiring solution designed for high-performance engine management and custom fuel injection tuning. Built by FuelTech USA—a trusted name among serious engine builders and competitive automotive enthusiasts—this harness bridges your PRO550 or PRO600 engine control unit to OEM and aftermarket ignition systems across Chevrolet and Chrysler platforms. Whether you're tuning a carbureted big-block, a modern LS engine, or a classic Mopar V8, this harness provides the critical signal pathways required for accurate spark timing control and engine optimization.
The FTSPARK-8 harness employs eight-channel spark control architecture, allowing independent ignition output management across all cylinders for true cylinder-by-cylinder fuel and timing optimization. FuelTech's engineered connectors and shielded wiring minimize electromagnetic interference—critical when running tight engine bays with alternators, fuel pumps, and high-amp electrical systems. The harness pinout is pre-configured for direct integration with Chevy and Chrysler ignition modules, eliminating guesswork during installation and reducing troubleshooting time during dyno tuning. Each conductor is selected for durability under sustained high-RPM operation, making this harness suitable for street machines, race vehicles, and turbocharged or supercharged builds that demand absolute ignition reliability.
This harness is essential for any serious Chevrolet or Chrysler engine builder migrating to FuelTech EFI management systems or upgrading from carbureted ignition to fully programmable spark control. Installation requires basic electrical knowledge and familiarity with your engine's existing ignition layout; comprehensive FuelTech documentation ensures proper termination at both ECU and engine-side connectors. The 18.5-inch length provides routing flexibility in cramped engine compartments, while the compact 2-inch cross-section minimizes clutter near manifolds and cylinder heads. Ideal for competition vehicles, restomod classics, and street-strip builds where ignition precision directly impacts horsepower delivery and engine longevity.
