Haltech Elite Fuel Management System

Haltech Elite 550 ECU & Swap Harness Kit

Drop a high-performance 1995-2004 Tacoma 4-Cylinder engine into your classic Hilux or 4Runner without the custom wiring headaches. When you swap a newer 2.4L (2RZ-FE) or 2.7L (3RZ-FE) powerplant into an older chassis, integrating the engine electronics and factory dash instrumentation is always the ultimate bottleneck. This comprehensive engine management and standalone swap harness kit completely eliminates the guesswork. Engineered by the EFI specialists at SNP Speed Innovations, this system is tough enough to handle intense motorsport punishment while ensuring your engine operates at peak efficiency in the trail, street or racecourse.

Built specifically for manual transmission vehicles only, this elite kit features a premium, made-in-the-USA conversion harness paired with a dedicated RZ Swap Dash Harness. This dual-harness setup ties the advanced Haltech Elite 550 ECU directly into your vehicle's critical sub-systems-allowing you to drop the factory Mass Airflow (MAF) sensor, discard failure-prone original wiring, and hook up your cabin accessories in roughly a single day.
