SAFC Installation Harness

The Apexi 401-A907 is an installation harness designed to work with the SAFC (Super Air Flow Converter) piggyback fuel computer. This harness is intended to modify air-flow meter or pressure sensor signals to optimize fuel delivery in various vehicles. It is a universal fit part, meaning it is not made for any specific car installation but can be adapted through custom work or professional installation. This harness serves as a critical link between the SAFC unit and your vehicle's engine management system. By intercepting and modifying signals from sensors like the airflow meter or MAP sensor, it allows for precise adjustments to the air-fuel ratio, potentially leading to improved engine performance and efficiency. The Apexi SAFC, when used with this harness, offers user-definable fuel correction points to fine-tune engine operation. It is important to note that this specific harness, part number 49A-A008, is discontinued and no longer available as new. Adapting this universal harness to a specific vehicle may require custom wiring or modification, and the seller cannot guarantee its compatibility with every car. If you are unsure about fitment or installation, it is recommended to consult with a professional or contact the seller for advice.
