Show original supplier description
This harness allows for direct connection from the ignition coil to both the flex fuel sensor and the ECM (Engine Control Module). The harness is explicitly stated as being custom-made, with customers required to specify the desired wire lengths from the ignition coil to the flex fuel sensor and from the ignition coil to the ECM during the order description. This ensures a tailored fit for individual installations. DSX Tuning emphasizes the quality and origin of their products, highlighting that this flex fuel harness is MADE IN AMERICA. They also express a commitment to supporting their customers, aiming to ensure end-users achieve maximum performance from their vehicles.
