Alright so I am looking to wire all three of my gauges using add a fuse. My question is if I want them to turn on and off with the car do I put all three power wires from the gauges into one add a fuse and put that into the radio fuse slot or do I need to use 3 different fuse slots with three different add a fuses for each gauge? I have 10 add a fuses so that is not a issue I am just curious
