Which one is "positive" +, Green or Yellow?


I assume Red is positive vs Black, but not sure about Green vs Yellow.

It seems Green is the positive one, am I wrong?

Black and Green are the common and Red and Yellow are the hot. So I suppose that means Black and Green are the negative and Red and Yellow are the positive.
