red would be power, black would be ground. not much else to it. the black can go on any unpainted screw (which is why it has the metal "circle"). the red wire would most likely go to the fuse box under the dash. just hook it into the fuse for the instrument lights or whatever. you can put the wire to where the fuse would go in, then shove the fuse in, making sure the wire goes in too. that's the easiest way to do it.
