MS3Pro EVO+ Flying Lead Wiring Harness

The AMP EFI MS3Pro EVO+ Wiring Harness Package provides a comprehensive and flexible solution for integrating the MS3Pro EVO+ ECU. This 8-foot flying lead harness is meticulously designed to support the full I/O capabilities of the ECU, making it ideal for custom engine swaps, standalone ECU projects, race car rewiring, and retrofit EFI conversions. Constructed with high-temperature, automotive-grade wire, this harness is built to withstand the demanding conditions of engine bays, including heat and vibration, ensuring long-term reliability. It utilizes white, black, and gray AMPSEAL connectors, offering secure and robust connections. The inclusion of long pigtails further enhances installation flexibility, allowing for precise routing and connection in various custom applications. Installation is streamlined thanks to the thoughtful design of this harness. Each wire is clearly color-coded and printed with its specific function, which significantly reduces guesswork, saves valuable build time, and simplifies troubleshooting or future diagnostics. This attention to detail ensures a more accurate and efficient wiring process for both experienced builders and those new to standalone ECU setups. While this harness is designed for universal application with the MS3Pro EVO+ ECU, specific fitment and compatibility with particular engine types (such as GM LS, Ford Coyote, Bosch Motronic, and New Hemi) are determined by the capabilities of the MS3Pro EVO+ ECU itself. Users should consult the MS3Pro EVO+ ECU documentation for detailed engine support information.
