someone have the fuse diagram for a 90 mustang gt
thx

 

If I'm not mistaken, the 1990 5.0 fuse box will look the same as the 1991 fuse box.

thx body
look exactly the same

 

NP This is the third fuse question I have seen here in 2 days, lol. Seems to be a problem all of a sudden

 

would u like a 4th fuse question? haha... the fuse that controls my dash lights doesnt work. the fuse is good but the lights still dont come on... before the dash lights would work if i turned the headlight switch on to a certain spot which kept the dash lights and taillights on, but now i can turn the headlight switch on like normal and all the lights work fine except the dash lights... i was thinking maybe the panel dim switch is bad? im gonna take apart the dash to see if i can find the problem... thanks

 

Sounds like the switch is going bad to me too. Try wiggling the switch and see if that does anything. If it does, you know you have a bad switch. If it still doesn't do anything...well..you still probably have a bad switch
