FT700 C&D Harness 10ft

The FT700 C&D Harness 10ft from FUELTECH USA is an essential fuel injection system component designed for serious engine builders and performance tuners who demand precision fuel delivery control. This 10-foot harness serves as the critical communication backbone between your FuelTech ECU and fuel injector drivers, enabling clean signal transmission and stable closed-loop fuel mapping across the entire RPM range. Whether you're building a street engine, drag racing platform, or high-output forced induction setup, proper harness routing and shielding directly impact fuel atomization, combustion efficiency, and overall engine response.

Engineered with shielded twisted-pair construction, the FT700 C&D Harness minimizes electromagnetic interference and cross-talk that can degrade injector pulse width signals—especially critical when running high-amperage ignition systems or tight engine bay layouts. The 10-foot length provides substantial routing flexibility, allowing installers to keep signal wires away from high-voltage ignition harnesses, power distribution, and heat sources that degrade insulation integrity over time. FUELTECH's engineering ensures impedance matching and termination standards that preserve signal fidelity at all engine speeds, from idle vacuum resolution to wide-open throttle transient response.

This harness is ideal for FuelTech FT700 EFI systems used in carbureted engine conversions, LS swaps, classic car restorations, and competition vehicles where factory wiring is absent or unsuitable. The 10-foot length accommodates remote ECU mounting locations common in vintage drag cars, road race builds, and engines with unconventional bay configurations. Proper installation involves routing away from starter motors, alternators, and fuel pump relays—practices that separate professional tuning shops from amateur installations and directly translate to stable, repeatable fuel delivery and drivability across all load conditions.
