Description
FuelTech LS550 V8 complete harnesses are the best fit for a standalone LS swap utilizing the FuelTech FT550 or FT550LITE ECU and GM LS engine. These plug-and-play harnesses come pre-terminated to suit an LS engine with all relays and fuses for a simple 3-wire battery hookup and ignition power. They are ready for both 58x and 24x triggers with provision for direct connection to LS3-style ignition coils, GM-style flex fuel sensor, and dual wideband Nano connection. FuelTech's LS550 harnesses are set up for both cable and drive-by-wire based throttles, with the connector for a GM-style accelerator pedal on the cabin side of the harnesses. Each connector has its own label and the connectors and harness insulation are heat, moisture, and oil-resistant.
