Function: The red power line of the injector plug is responsible for transmitting the power signal to the injector. When the engine starts, the ECU sends current to the injector power line to start the injector, and the injector starts to spray fuel.
Waterproof Performance: The shell of the injector plug is made of waterproof and flame-retardant material, which is durable and not easy to break, and can withstand use in various environments.
Black Control Line: The black harness control line of this connector is responsible for transmitting the control signal. When the fuel supply needs to be increased or decreased, the ECU sends a signal to the injector control line to control the switch of the injector.
