How is the spark plug of Wuling Hong Guang divided into positive and negative?

Wuling Hong Guang's throttle plug has a protruding buckle. It is normal to insert the plug according to the position of the buckle, otherwise it cannot be connected.

Nowadays, electronic throttles are all controlled by on-board computers. When the driver steps on the accelerator pedal, the sensor under the accelerator pedal will send a signal to the on-board computer, and the on-board computer will control the accelerator according to the received information.

Therefore, when installing or replacing the throttle valve, the throttle plug must be connected correctly according to the assembly requirements. It's best to ask a professional mechanic to finish it.
