How to connect Link 03 and lens line group?

The wiring method for adding the lens line group to Link 03 is as follows.

1, you need to find the main switch at home before wiring, and you must be in a power failure state before you can proceed to the next step. Then find the connected wires and distinguish the live wire from the neutral wire. Generally speaking, red is the fire line and blue is the zero line. If you are not particularly clear, you can also use an electric pen to test. The bright one is the fire line, and the other is the zero line.

2. Mark and cut the thread. Prepare a pair of pliers, peel off the insulation in front and expose the copper wire inside. Be careful not to be too short. Then pinch off the skin on the four heads and connect the wires.
