Yeah, I have that little red scrap of paper there and only the black arrow and hot can me made out. So naturally I connected the hot wire there. Another blown gauge. I could not be more frustrated with this. This should not be frickin rocket science. This is the third blown gauge. I should have just replaced all this ancient crap with Dolphin gauges and called it good. I would have had less money in it. I cant believe with all the good info and knowledge on this site I cant get the answers needed to wire one little Chinese crap gauge. SOrry. Just blowing steam.
