PRO550 V8 Complete Harness Chevy/Mopar

The PRO550 V8 Complete Harness for Chevy/Mopar engines is a professional-grade engine control harness designed to connect the FuelTech FT550 ECU to GM and Mopar V8 platforms. This complete harness eliminates the need for custom wiring fabrication, delivering a plug-and-play solution for builders transitioning to standalone fuel and ignition management on Gen III/IV small-block Chevys and modern Mopar V8 engines.

As a complete engine control harness, this unit integrates all sensor inputs, injector outputs, ignition firing signals, and auxiliary circuits required by the FT550 platform. The harness is engineered to OEM connector specifications for Chevy and Mopar applications, ensuring reliable signal transmission and eliminating compatibility guesswork. At 9.95 lbs, the assembly is compact enough for tight engine bay installations while maintaining full gauge length and terminal quality. The pre-assembled configuration significantly reduces installation time compared to building a harness from individual wires and connectors, a critical advantage when working within the precision tolerances modern engine management demands.

This harness is essential for street rod builders, race engine builders, and shop technicians upgrading classic or modern V8 platforms with fuel injection and programmable ignition control. Whether you're converting carbureted power to sequential fuel injection, optimizing a crate engine installation, or retrofitting OEM fuel systems with aftermarket tuning capability, the PRO550 V8 eliminates integration complexity. The complete harness approach is especially valuable for Mopar V8 conversions, where proprietary connector styles and wiring diagrams vary significantly across model years. Having a pre-mapped harness designed specifically for your platform reduces troubleshooting time and ensures all sensor signals and output circuits function as the FT550 ECU expects them.
