I am planning installing my own DIY fuse/relay panel in the glove compartment of my 50 Chevy with SBC, Alternator and HEI. I want to use halogen headlights and electric fuel pump so I'm upgrading to relays. I don't plan on any other fancy accessories, no power windows, no A/C... I was just about ready to dive in, when I started reading about Negative Relay Switching? My question is, with a 60 amp alternator and minimal accessories, do you think I need to go Negative Relay Switching for increased safety? I'm not a master in electrical but I am doing my best to figure it out. I just don't want to burn my truck down.
