Toyota Repair: Horn, toyota 4runner, 12 volt

Question
I have a Toyota 4runner 1988, the horn doesn't work, I checked the fuses box to replace it but I don't know which one is the fuse for the horn, the cover with the instruction is gone

Answer
The is an easier way, you'll need an inecpensive 12 volt test light, the horn fuse is hot all the time, I believe it's in the panel on the left lower dash but it may be under the hood. just use the testlight to touch both sides of all the fuses, the one that only lights up when touching on contact on top of the fuse is the one that is blown.
