Professional Integration for the Elite 550
The Elite 550 Premium Universal Wire-in Harness is designed to elevate the installation of Haltech’s entry-level Elite 550 ECU. The Elite 550 is perfect for basic 1-4 cylinder or simple V8 applications, and this Premium harness ensures that the wiring supporting it is anything but basic. By incorporating a molded fuse and relay box directly into the loom, this kit solves the challenge of providing safe, switched power to your injection and ignition systems without requiring complex custom wiring.
Engineering for Reliability
The Premium harness is built with 2.5 meters of high-quality, color-coded automotive wire. The integrated fuse box houses 2 relays and 4 fuses, which are pre-wired to handle the essential tasks: powering the ECU, the fuel injectors, the ignition coils, and the fuel pump. This separation of circuits ensures that a fault in one component (like a shorted O2 sensor) will blow a single fuse rather than taking down the entire engine management system. The harness also features shielded wiring for the CAS inputs to prevent noise interference.
