*For the BMW S58 JB4 platform connect the white wire to position #4 on the JB4 25 pin harness. Select WMI Ethanol Setup option 0 to enable pin location 2/3/4 flex fuel input.
*We have also made it optional to purchase all the items ala-cart should you choose but for the kit to work it must include the Fuel Lines, Ethanol Sensor, and Analyzer.
*For CANflex adapter JB4 & MHD use engine bay CANbus connections in our guide. BM3 requires connection to CANbus wires on BCM module under passenger side dash or at the DME.
*If you aren't sure whether this kit fits your car, send us a picture of your engine bay with the engine cover removed to info@fuel-it.com
*Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated your ethanol readings may be artificially elevated.
*Free shipping in USA on complete kits only.
