Why You Need This
When building custom harnesses for engine swaps or aftermarket ECU installations, generic automotive connectors create weak points that fail under vibration, heat, and moisture. The TYCO 12-pin connector system is what Haltech specifies for their professional harness assemblies—proven in motorsport and high-performance street applications from drift cars to time attack builds.
This plug assembly eliminates the tedious task of sourcing individual pins and housings, providing everything needed for a proper connection point. Whether you're adapting an LS swap harness for a Haltech Elite, building custom sensor extensions for a turbo RB25, or creating breakout connections for a 2JZ build, this connector ensures your wiring maintains the same reliability standards as the ECU itself. Poor connections cause intermittent faults that are nightmare to diagnose—invest in proper hardware from the start.
ECU & System Compatibility
Compatible with the full Haltech Elite and Nexus range including Elite 550, 750, 1000, 1500, 2000, and 2500 models, plus Nexus R3 and R5 systems. Widely used in Haltech harness assemblies and recommended for any custom wiring applications requiring reliable 12-circuit connections. Contact our team to confirm fitment for your specific ECU and harness requirements.
