Fuse box layout

My fuse cover shows the various locations, what year car do you have?

unfortunately my chilton manual only covers 94-98. on mine as well as 94, and 95, I don't know what yours looks like, but it is cavity #2 looking at my book, there is a circle in the bottom left corner, on the top there are 3 slots, from left to right, there should be a 15 amp fuse, next to that is the 30 amp fuse, that controls windshield wiper-high, washer pump. and the slot on the other side is not used. on my cobra, if you take off the fuse cover, the middle fuse almost in line with the hood release, on the side closest to it. it's green. You could also try to find the 12v source for one of your amps in the trunk rack, and not mess with running a wire, but I ran mine off of the radio fuse, which keeps power to the clock, and had to put an inline switch to turn off my amp. Good luck
