A problem on the blue wire doesn't explain the horn and brake light not working or maybe I read your first post wrong. Do they already work?

Maybe there is more than one issue? :eek

Den den den!!!! :lol There must be a problem that's stopping the 12V feed in the right handlebar switches. The signalling circuit is the 12V feed into the switches that's why I was suggesting it. When he put 12V on the blue wire it must have gone back through the light switch and powered the horn and the brake lights. I bet if he put 12V on the blue wire and turned the light switch off the horn would stop working :lol
