Flex Fuel Kit — Gen 5 Truck (Simplified)

The simplified harness for 2014–2018 Gen 5 LT trucks, which wire differently from the rest of the Gen 5 range.

• 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 signal input at the ECM. Pinout is included.
• Fits: 2014–2018 Gen 5 LT trucks (L83 / L86) on E92 / E92A. Other years take the standard 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 ECM has to be calibrated to read the sensor. This kit is the hardware only.
