Flex Fuel Kit — Holley Terminator X

For engines running a Holley Terminator X. The sensor feeds Holley’s own flex fuel input, so the blend is handled in the Terminator X software rather than a GM PCM.

• 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: Wired to the Terminator X flex fuel input.
• Fits: Any LS or LT running a Holley Terminator X. 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: flex fuel has to be set up in the Terminator X software. This kit is the hardware only.

Sold for off-road / competition-use vehicles only.
