I'm having trouble figuring out which wires are which. I have a light bulb type thing that has a wire connected to a peice of metal so that when I touch something with the metal peice that has electricity the light bulb lights up, and the only wire that has power is the blue wire. The yellow wire (which I though was the constant) has no power and the red (thought it was ACC) has no power either. Theres also two green wires, some orange wires a black wire and etc etc. Any help would be appreciated! Thanks.
