Depending on those wires that caused the arcing, I doubt that it alone caused any problem. I don't have a wiring diagram for your truck but I assume the horn circuit has a relay on the firewall, the horn button should pull the relay in and the relay carries the heavy current for the actual horn. Lighting should be pretty simple, the headlight switch having 2 positions, 1st position should be parking/running lights fore and aft, second position should be headlights and rear running lights. The wiring at the headlight switch may be on the wrong terminals. The only fuse in my 1957 is incorporated in the headlight switch, it only handles the gauge lights and dome light. A fuse block was optional equipment on my truck, maybe yours also. Brake lights do not run through the headlight switch, you should find a brake light switch that is actuated by the peddle arm, one wire in and one wire out of that switch, one of them should be hot all the time, the switch just disconnects or connects those 2 wires.
