    I do not know but why is the one that is a problem the one you cannot read? Looks like it says ign switch some kind of relays and accessories. Use a process of elimination. Something like pull all the relays, F7-A related first. Turn the key on, did it blow? Continue on the best logical path you can. Fuses. breakers, chassis and engine harness type disconnect to narrow it down.
