do you have power coming out of the horn relay after you press horn button? you should have a constant 12v to the horn relay but if nothing comes out then the relay is bad. as far as brake lights you should have brake light switch under dash attached to brake pedal. you can make a jumper wire to bypass the switch to see if switch is bad. and do you have auto or manual tranny? for reverse lights?
If you can't fix it with a hammer and a welder then your gonna need a new one!
