Tools we need:

Select the correct menu based on the mark of the module.

Click [Guide] at the bottom left to check the best connection method.

Click [Back] at the bottom right, then click [Pinout] at the bottom left to check the diagram.

Then we connect the harness according to the wiring diagram.
