Take out the plug and remove it horizontally. There are no nails. Gently pry it open with a screwdriver, pull out a red-brown wire, and tie up the red+class indoor lamp in the middle of the adapter circuit board that was originally connected to the cigarette lighter. Tie the thick black and brown wire and plug it back in. Note that each generation of models may have the same color, but the red ones are positive and negative. After insertion, you can test the card and tie it back to the connector with insulating tape to avoid pulling it out. This installation is difficult to pull out the plug, and it is easy to pull out the broken wire when it is broken. Hehe? That's all!
