Wiring Harness Soft Touch HEI

The Wiring Harness Soft Touch HEI by QUICKCAR RACING PRODUCTS is engineered for serious enthusiasts upgrading to High Energy Ignition systems in classic and modified vehicles. This harness simplifies the conversion process, eliminating the complexity of routing custom ignition wiring while maintaining OEM-style reliability and appearance. Whether you're building a street rod, restoring a muscle car, or upgrading a track vehicle, this harness bridges the gap between modern ignition performance and original vehicle architecture, saving hours of fabrication time.

Built with soft touch insulation, this wiring harness resists chafing, heat damage, and vibration—critical factors in engine bays where temperatures fluctuate and components move under load. The soft touch jacket provides superior flexibility compared to standard PVC harnesses, allowing easier routing through tight engine compartments without crimping or kinking conductors. Manufactured by QUICKCAR RACING PRODUCTS, a trusted brand in performance ignition systems, this harness features properly gauged wire and secure connectors designed to handle the higher current demands of HEI distributors while maintaining clean, factory-correct aesthetics under the hood.

This harness is ideal for builders converting from points-based or weak stock ignition systems to high-output HEI units, delivering stronger spark and improved engine reliability across all RPM ranges. Installation requires no welding or permanent modifications—simply disconnect the original harness and integrate the new one into your vehicle's existing electrical system. The compact design (8.05 x 1.3 x 12.4 inches, weighing just 0.57 lbs) fits most under-hood layouts, making it compatible with a wide range of classic American vehicles and modern engine swaps where HEI conversion is desired for improved starting, throttle response, and overall driveability.
