I like this switch, it's decent if a little flimsy but NO schematic. Really how hard is it to turn one on? It means "we don't care". The switch goes with 4 BLACK WIRE. I FEEL LIKE A PROFESSIONAL BOATBUILDER. It is wrong to point out serious wiring errors. Black is always grounded, red is always powered. There are no red wires for the specified power supply. It took me an hour to figure out how to even get the horn to work. Yes, I used a red wire and a new terminal to connect. I will never buy from such a lazy company again. The one that says, "The 7th photo is the schematic. this is a joke loss of customer relationships.
