Haltech Flex Fuel Composition Sensor Plug & Pins

This is the Haltech Flex Fuel Composition Sensor Plug and Pin kit, part number HT-011001. It's what you need to make a clean, reliable connection for your flex fuel sensor, which is crucial for modern engine management systems that adjust fuel mixtures based on ethanol content. Getting this connection right ensures your engine control unit (ECU) receives accurate data about your fuel composition.

This kit includes the necessary plug and the individual pins that go inside it. You'll use this to build a custom harness or repair an existing one, ensuring a solid connection that won't come loose or corrode over time. A well-made connection here means your ECU can properly interpret the sensor's readings, allowing for optimal engine tuning whether you're running pure gasoline or a blend with ethanol.
