1. First, we take a live wire from the bathroom circuit in the distribution box at home and connect it to the switch entrance. Then we use wires to connect the upper openings of the blower (or lighting), rearview mirror headlights, heater 1 and heater 2 with the ventilation buttons, that is, the live wire connection of the upper openings of each button is completed.

2. Next, connect the control line of Yuba, and connect the blower (or lighting), rearview mirror headlight, warm air 1 and warm air 2 respectively, as well as the wires connected to the blower (or lighting), rearview mirror headlight, warm air 1 and warm air 2 from the lower mouth of each switch button for ventilation, so that the control line is connected.

3, from the blower (also can be lighting), rearview mirror headlights, air heating 1 and air heating 2, take a zero line from each of these devices, and then connect this zero line to the zero line of the bathroom circuit. If there is a ground wire, it also needs to be connected to the shell of each device.
