Connecting a CORE standalone ECU to a Gen IV 58x LS engine running drive-by-wire throttle control calls for precise, ECU-specific wiring rather than factory splices. The HP Tuners COR-HAR-002 handles that connection directly, arriving with 37 terminated leads wired to CORE-specific pinouts and additional labeled open leads for the sensor and accessory circuits that vary by build.

HP Tuners COR-HAR-002 Installation Notes:

• Terminates 37 connections directly to the CORE ECU connectors for Gen IV 58x/4x applications.
• Measures 4 ft. in length, matched to typical CORE ECU mounting locations in the engine bay or cabin.
• Includes labeled open leads for ignition, injector, and sensor circuits specific to the engine build.
• Built for drive-by-wire Gen IV 58x LS engines; Gen III 24x drive-by-cable builds require the COR-HAR-001 harness (sold separately).
