Fuse panel?

[sirspook16]

My co-worker has an 87 cougar and we just put in a cassette deck (yeah, he's old :} ) just so happens we popped a fuse and the dome light went out, we changed that fuse and the speed indicator (only shows numbers for speed, no needle to the number) went out. the dash lights still work though. is this a fuse we overlooked or one of the bigger fuses i cannot check with my eyes?? help me i'm stuck!
