Elite 2500 + Basic Universal Wire-in Harness Kit Length: 2.5m (8′)

Engineered for Custom High-Performance Builds

The Elite 2500 + Basic Universal Wire-in Harness Kit is the foundational system for builders and tuners demanding absolute control over sophisticated engine configurations. This kit pairs Haltech’s flagship Elite 2500 ECU with a robust, 2.5-meter universal wiring loom, providing the blank canvas necessary for custom engine swaps, race car wiring, and unique multi-rotor or multi-cylinder applications. It is the definitive choice when plug-and-play solutions do not exist or when a bespoke, mil-spec quality harness is required.

Advanced Engine Management Architecture

At the heart of this package is the Elite 2500 ECU, a powerhouse of processing speed and I/O flexibility. It supports engines ranging from 1 to 12 cylinders and 2 to 4 rotors, handling sequential injection and direct fire ignition for up to 8 cylinders (or 4 rotors) natively. The unit features a waterproof case and Drive-By-Wire (DBW) throttle control, making it compatible with modern electronic throttle bodies for precise idle control and rev-matching. Its dual-channel knock control and long-term learning capabilities ensure engine safety and optimal performance under all conditions.

Universal Wiring Flexibility

The included “Basic” Universal Wire-in Harness is designed for the fabricator. It comes pre-terminated with the Elite 2500 ECU connectors on one end, while the engine side features unterminated, color-coded, and labeled wires. This allows the installer to cut each wire to the exact length required for a clean, tucked installation, eliminating the mess of excess cabling. The harness uses high-quality automotive-grade wire (TXL) to withstand the harsh thermal environment of the engine bay.
