BEFORER you get into the cut/splice/repair mode... look for the WSM (WorkShop Manual ) to get the wiring diagram !!
Real curious as to WHAT the spliced wires go to !!!
While you 'could' tape over lightly charred wires, far better to cut/solder/splice using SAME coloured/ gauge wire, or 'ugh'..... a new harness($ 600 ?).Kub Cda show harness,comes with fuse panel and fuses.

Have a very,very careful inspection of each wire,'feel' the plastic, BEND the wires ! If plastic is 'compromised', it'll crack or snap chunks off. Heat kills copper,so if insulation is 'hard stiff', replace.
Me, I'd replace the harness before buying a new hood. Having 'electrical' issues, months from now,in the dead of Winter would NOT be fun.Painful too, form kicking yourself while saying 'I should have....' , 1000 times.
