Brake light issue

Hello everyone, looking for some help since the service manual was not so clear.
I installed an air horn to the same line as the old horn, was working fine for awhile then just stopped. When it stopped working, the brake lights also stopped working. If I press the brake pedal or pull the lever I get nothing.
Obviously the horn and brakes are on the same line, but the schematics show no fuse for it.
My question is could it be a relay? But where is it?
Any help is appreciated.

UPDATE:
I will be checking the fuse box first to see if everything is in order. Hopefully it will be there.
Once I correct the problem, I was thinking of either putting in a bigger fuse or adding an inline fuse to the air horn. Any suggestions?

An airhorn? does this airhorn use air? Or does it just draw a lot of juice to sound like an airhorn?
Since an airhorn is not stock, trace down the wiring, see where it's spliced into. Look for problems at the splices.
I don't think it's a good idea to increase the size of the fuse.

You need to check the amp draw for the air horn. Overloading a circuit is ng.... Putting a bigger fuse in is asking for burnt wiring if the draw is too much for the wiring size.
