*For the BMW G-series JB4 platform connect the white wire to position #4 on the JB4 25 pin harness. Select WMI page bit 2 to enable.

*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 [email protected]

*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.
