Fusible Links Wiring for 1980 Datsun 280zx

Can anyone please provide me with pictures of the wiring surrounding the Fusible Links box? Preferably both the top side under the lid and underneath where the wiring goes in.
I recently purchased my first Z car its a 1980 280zx and someone had previously started redoing the wiring and didn't finish so there are a bunch of wires missing from the area around the battery and the fusible links box, including the positive terminal lead for the battery which is also completely missing. I haven't been able to find a good place that shows which wires go to the fusible links box and which go to the other fuses in that area so any info, pictures and diagrams would be greatly appreciated.
I have included some pictures of the area I am referring to which will hopefully provide some context. The first picture is what I've been referring to as the fusible links box, if it's called something else please let me know. Thanks in advance
