Fuses I have rewired my truck ( a 55 2nd series 2800) It had no fuse box , It did have a fuse on the heater circuit and its a 15 amp . my suggestion for the rest if you addinga fuse box is to look @ one from a 60's model truck and use the same amp they run for the circuits respectively. I f you have an AC unit, Most run a 25 amp fuse
more fuse info you can use use law to figure what amp fuse you will need for most however the fuse boxes on most are marked or you can find it in an electrical manual for Chevy trucks.
