VCC Power ON Switch Signal ADJ Brightness Control GND Ground. Tip: Connect to the LCD high voltage board in the same way. 2: Use the multimeter to measure the number of lines that the LED light bar connection line supplies. Which number are the negative lines? Which lines are the negative lines? There are only positive and negative points in the line, and the technology should not be used. See the light bar to see it. Tip: The power supply of the LED strips are the same. They are all connected together.        The number of sets of negative poles represent th number of sets of series circuits. CN1: Power supply Power switch signal Brightness control Ground wire Ground wire. LED connection must pay attention to the interface definition. Only the positive and negative points, the positive input power supply must not be reversed or connected wrong.
