geez, ask for the moon!
there's not that many fuses on the original panel [only 7], and some of those weren't options for the truck most 5-9 years [AC, clock, spot]
note that there's 'accy' fuses [3] with a total of 7 terminals, no doubt all small stuff like hood light went to a single fuse
Heater [delux] 9amp
Fogs 14amp
Backup isn't specified, small, like 3-7 amp
others??
well, it's a start
