After connecting the positive and negative terminals of the light board, route the wiring from the side to the circular hole at the back of the board. Use two M3×20 screws on the edge, then simply cover it with the cap.

The wiring sequence is as follows: connect the battery’s negative terminal to both the protection board’s negative terminal and the light board’s negative terminal.

Connect the battery’s positive terminal to switch pin 1 and the protection board’s positive terminal; connect switch pin 2 to the light board’s positive terminal.
