yes lyon that small post would have to be energized by a 12 volt power source such as a wire that comes off your starter switch. the post you would hook it to, would be one that has power coming from it only in the start position. Once you turn loose of the key, it should not send any more power to it. One of the large post on the solenoid should be hooked straight to the battery and the other side goes to the large post on the starter. the battery side is usually marked as [bat].
