Show original supplier description
The Fueltech FT550 K Series Standalone Engine Harness is engineered for Honda K20 and K24 engines, integrating a fusebox for a streamlined setup. This standalone harness offers a robust solution for engine management. Installation requires specific components and considerations. A charge harness must be run separately, as it is not included with this product. Additionally, the harness is incompatible with resistor boxes, requiring the use of high-impedance injectors. For race car applications that lack an interior harness or dashboard, a switch panel will be necessary, though one is currently in development. Compatibility extends to various chassis types, including EF, EG, EK, and DC2 models, as well as other universal applications, providing flexibility for different build configurations.
