brake lights will not work. Very hard to see or figure out what fuse is what-which on e is for the brake lights? I see 6B but it says is uses a 20 fuse-there is no 20 at that spot. Forget changing ou the brake switch-couldn''t get it off. 1994 Olds 88Royal-100,000 miles.
Great engine

 

if it does not have a 20 amp fuse maybe thats what it needs. just a guess. i dont think the fuse box will lie. good luck.
