Also: (I had a math teacher do this!)
In math, black is for numbers greater than zero, or positive, and red is for numbers less than zero, or negative. DON'T CONFUSE MATH AND ELECTRONICS!!! LOTS OF SMOKE AND BAD SMELLS!!
Red is ALWAYS positive in electical systems, and you should color-code your wiring correspondingly. Black,or sometimes green, but mostly black, is Negative (actually ground, but it's easier to think of it as negative sometimes)
White is signal, and, unless you use other sensors, that's it.
I had a math teacher try to jump a car. Melted his battery, he did.
