Harnesses connect a FuelTech ECU to the engine, sensors and accessories. The range runs from pre-terminated engine harnesses to bare unterminated looms, plus adapter harnesses, plug-and-play vehicle harnesses and the connectors to build your own.
Complete harness — pre-terminated for an engine family, with relays and fuses built in. The FT550 LS GEN IV harness, for example, supports 58x and 24x triggers and LS3-style coils.
Unterminated harness — ECU connector on one end, loose wires on the other, for custom installs. The FT550 needs both A and B harnesses; the B harness alone is for FT450 upgrades.
Adapter harness — moves an existing installation to a newer ECU, or links accessories such as peak & hold drivers and wideband controllers.
Plug-and-play vehicle harness — plugs into the OEM harness on supported PWCs, UTVs and motorcycles.
Connector and plug kits — for repairing a harness or building one from scratch.
Match the ECU model. Harnesses and connector kits are ECU-specific. Check that the listing names your ECU (FT450, FT550, FT600 or FT700) before ordering.
