Zeitronix ECA Harness

This harness is designed to plug directly into standard GM-style flow-through ethanol content sensors, which are commonly used in aftermarket Flex Fuel systems.

The harness is 8 feet long. This generous length allows you to mount the sensor in the rear of the vehicle on the fuel return line while easily reaching the ECU or gauge in the front.

The harness provides the necessary wiring for 12V power, chassis ground, and the digital signal output required to transmit ethanol content and fuel temperature data.

Yes. One end features the specific automotive-grade connector that clips securely into the ethanol sensor, while the other end is loose wire for custom connection to your specific ECU or gauge.

Absolutely. It is constructed using high-quality automotive wire and connectors designed to withstand the vibration, heat, and potential chemical exposure found in performance environments.
