Why You Need This
Six-cylinder engines demand precise ignition timing across all cylinders to unlock their full potential, whether you're building a 500hp street RB25DET or a 1000hp 2JZ drag car. The Elite's individual cylinder ignition control allows for cylinder-specific timing adjustments — critical when dealing with uneven fuel distribution in turbo applications or compensating for manufacturing tolerances in rebuilt engines. Without proper ignition harness design, you'll face voltage drop, EMI interference, and the nightmare of troubleshooting misfires that could be wiring-related rather than tuning issues.
This Universal I6 harness solves the complexity of connecting six individual ignition outputs from your Elite ECU to modern coil-on-plug setups or conventional distributor-less systems. The IGN-1A configuration provides the current capacity needed for high-energy coils whilst maintaining the signal integrity essential for accurate timing control. We've seen too many promising builds compromised by inadequate ignition wiring — this harness ensures your Elite ECU can deliver the precise spark control these engines deserve.
ECU & System Compatibility
Designed specifically for Haltech Elite 2000 and Elite 2500 ECUs, providing direct connection to the ECU's IGN-1A ignition outputs. The universal design accommodates various I6 engine platforms including Nissan RB series, Toyota 1JZ/2JZ, BMW M54/N54, and Ford Barra engines.
