Flex Fuel Kit — Gen 4/5 Kit (Car, SUV & Truck)

Adds ethanol content sensing to a Gen 4 or Gen 5 GM car, SUV or truck so the ECU can read the blend in the tank and fuel to it.

• In the box: OEM GM ethanol content sensor (Continental), braided stainless fuel line and adapter, install harness using OEM GM connectors, fuel line disconnect tool, and vehicle-specific pinout and wiring instructions.
• How it signals: Wires to a spare 5V / signal input at the PCM or ECM, depending on platform. Pinout is included.
• Fits: Gen 4 (LS3, L92, L9H, LC9, LY6) on E38 / E67, and Gen 5 LT (LT1, LT4, L86, L83, L84) on E92 / E92A. Covers all Gen 4 trucks and SUVs, and 2019–2022 Gen 5 trucks. 2014–2018 Gen 5 trucks take the Gen 5 Truck kit instead, and the 2016-and-newer Camaro SS takes the 6th Gen Camaro kit. Confirm your year and PCM with the vehicle picker before ordering.
• Reversible: it is a sensor and a signal harness. The hardware comes back out and the calibration returns to straight gasoline whenever you want.
• Also required: the PCM has to be calibrated to read the sensor. This kit is the hardware only.
