need wiring schematics for horn circuit

[missmouse]

anyone able to post these please?
im now convinced my intermittant horn fault must somehow be connected to the original Audi alarm/imbobiliser as i can find no fault in the horn operating circuit. Strangly although I have a cat1 Toad system the original system seems to be still in play as you can hear the extra horn in the rear quarter "honk" quickly when you arm the system!

also to add to above:
where exactly IS the original alarm control unit located?
