Wiring:
Two-in-one (voltage/temperature): connect the red wire to "+" and the black wire to "-"
Two-in-one (voltage/water temperature): The red wire is connected to "+", the white wire is connected to negative "-", and the yellow and blue wires are the water temperature sensor wires.
Three-in-one (voltage/time/stopwatch): connect the red wire to "+", the blue wire to the electric door lock "+", and the white wire to "-"
