If you have a pic n pull near you i would start looking there, all the fuses from early to mid 80`s should be the same, you can also look in the same year toyota cars, they use the same fuses as the trucks. also, the 80 amp fuse does not pull out like the other fuses, you will have to pull the fuse holder out of the fuse box and remove two screws to remove and replace that fuse.
