Ignition Harness Dual Box

The Ignition Harness Dual Box is purpose-built for high-performance ignition system upgrades and custom engine builds where dual ignition control is required. This weatherpack-sealed harness connects directly to dual ignition boxes and Quickcar-style switch panels, making it essential for fuel-injected engines, nitrous systems, and advanced ignition timing management setups. Whether you're upgrading a street machine, race car, or complex engine conversion, this harness eliminates the guesswork of custom wiring and ensures reliable signal transmission in demanding underhood environments.

Built with weatherpack connectors, the Ignition Harness Dual Box resists moisture, vibration, and temperature extremes that destroy exposed connections in high-output engine bays. The sealed connector design prevents corrosion and intermittent signal loss—common failure points in dual-ignition systems where timing precision is critical to engine performance and reliability. Measuring 8.15 x 2 x 12.65 inches and weighing just 1.07 lbs, the compact harness fits cleanly within tight engine compartments without sacrificing durability or electrical integrity, allowing clean integration with modern ignition control modules and switching solutions.

This harness is ideal for enthusiasts running standalone ignition systems, nitrous oxide controllers, or multi-coil setups that demand isolated trigger control and fail-safe switching. Installation pairs seamlessly with Quickcar switch panels and aftermarket dual-box configurations, making it the go-to choice for builders who refuse compromises on ignition reliability. Whether wiring a dedicated race engine or upgrading a modified street application, the weatherpack design ensures long-term durability where corrosion resistance and signal fidelity directly impact throttle response, idle quality, and peak engine output.
