What's the difference between Suzuki Langdi Zhongmen Line 3 and Line 5?

The words of the three lines are positive electrode, negative electrode and signal line. Generally, the yellow line is a signal line. Five wires, two energized and two grounded, 1 signal. The electronic accelerator pedal is actually that the accelerator opening is controlled by the motor, which cancels the accelerator line between the accelerator pedal and the accelerator. In other words, the driver's acceleration intention will be transmitted to the engine controller through the position sensor of the accelerator pedal, and the engine controller will adjust the throttle body through the motor. At the same time, the electronic throttle opening sensor feeds back the detected opening signal to ECU to realize the closed-loop control of electronic throttle opening.
