It works very well. Working voltage 12 volts. I have tested it with 5 volts and it works too. Do not connect to 220 volts because you will burn it. As it does not come with instructions I will clarify the doubt. Positive red wire 12 or 5, 6, 7, 8, 9, 10, 11 volts, never go above 12 volts. Negative black wire. Yellow and green wires are for the switch. I hope I have clarified your doubts. I repeat do not connect to 220v because you will burn the circuit. Greetings from Gran Canaria :-)
