Each LED strip has three connection points: the input connector, the auxiliary power wires, and the output connector. These can be seen in the adjacent picture, from left to right: auxiliary power wires, input connector, output connector. The strip uses 3-pin JST SM connectors. The input connector has three male pins inside of a plastic connector shroud, each separated by about 0.1â³. The black wire is ground, the green wire is the signal input, and the red wire is the power line.
