Elite 550 + Premium Universal Wire-in Harness Kit Length: 2.5m (8′)

The Tuner’s Foundation: Elite 550 + Premium Wire-in Kit

For custom builds where a plug-and-play solution doesn’t exist, the Elite 550 + Premium Universal Wire-in Harness Kit is the professional’s choice. This comprehensive package combines the entry-level yet potent Elite 550 ECU with a premium, 2.5-meter flying lead harness and a fully integrated fuse box. Designed for 1-8 cylinder or 2-rotor engines, this kit provides everything needed to construct a motorsport-grade electrical system from scratch. The “Premium” designation signifies the inclusion of a firewall grommet and a moulded Haltech fuse box with relays and fuses, ensuring a clean, reliable installation that is protected against shorts and environmental hazards.

Engineering for Custom Applications

The 2.5-meter harness is constructed with high-quality automotive-grade wire, color-coded and labeled to match Haltech’s schematics. It features a fully populated ECU connector on one end and flying leads on the other, allowing you to terminate to your specific sensors and injectors. The included fuse box simplifies power distribution, providing fused circuits for the ECU, injectors, ignition, and fuel pump, along with the necessary relays. This eliminates the need for messy, custom-made relay boards.

Operational Benefits

The Elite 550 offers robust control over fuel and ignition, supporting sequential injection for up to 4 cylinders and direct fire ignition. The wire-in nature of this kit allows for complete customization of the loom length and routing, resulting in a tidy engine bay. It supports advanced features like closed-loop O2 control, knock control, and basic boost control strategies. The kit is perfect for engine swaps, race cars, or classic restorations where modern reliability is required.
