1981 720 wiring issues

Recommended Posts

How’s it going  
I recently got a 81’ 720 4wd .

guy I got it from put a flatbed on it , has sat on his ranch for several years I got it home . Truck has no tail lights , brake lights . Signals, heater . Anything ... headlights work on and off , it doesn’t seem to be a wiring nightmare but any input on this and what It could be would be really appreciated. Also if anyone has a picture of the fuse block inside the cab I would greatly appreciate it . Mine is labeled with number 1- so on . But doesn’t list what fuse  is what . If anyone know which fuse controls what
