The working principle is as follows:
Power supply voltage supply: One or more wires in the wire harness are responsible for transmitting the power supply voltage from the battery to the fuel injector, providing the required working voltage for the fuel injector.
Signal transmission: Sensors (such as the throttle position sensor, intake pressure sensor, etc.) convert the detected engine operating parameters into electrical signals and transmit them to the ECU through the wire harness. The ECU calculates the optimal injection timing and injection quantity based on these signals and transmits the control instructions to the fuel injector through the wire harness.
Fuel injector action: When the fuel injector receives the control instructions from the ECU, it will open or close the fuel injector according to the requirements of the instructions, thereby realizing the accurate injection of fuel.

The motorcycle EFI (Electronic Fuel Injection) wiring harness refers to a system that connects various electronic devices, sensors, actuators, and the ECU (Electronic Control Unit) on a motorcycle through electrical wires. Its primary function is to transmit electrical power and signals, ensuring that the EFI system can operate normally. In the EFI system, sensors are responsible for collecting various data, such as engine RPM, intake air volume, oil temperature, etc., and transmitting these data to the ECU through the wiring harness. The ECU analyzes and processes the received data, and then sends instructions to actuators, such as fuel injectors and ignition coils, to control key functions such as fuel injection and ignition of the engine.
