*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 the Supra JB4 platform connect the white wire to position #4 on the JB4 25 pin harness. Select the WMI setup page and enable bit 0.

*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.
