use the positive siren wire to trigger a relay put it on pin 86, ground pin 85 of the relay put positive on pin 87 an use 30 as the output to the positive side of the airhorns .This will set the airhorns off while the alarm is going off and it will be constantly blowing you can also use a siren as well.

would it still have the same "pattern" as the normal siren output, you know, high pitch low pitch high pitch low pitch hig... you know...  typical siren, or just one steady 1 tone blow horn?

1 steady tone. You could add a flasher to have it pulse on and off like a factory alarm does with the horn.

i did it this it did not work this is what u do  tap  in to the  postive lead of the compressor  and connect it to #87   #85 to alarm siren output if output is (+)     connect #86 to ground  if #86 is (-) connect to 12 volt fused  connect#30 a constant 12v fused 20 amp  u will need a diode

alright, so if i put an airhorn with a flasher instead of a siren, would it be the same as a honk alarm, just louder? like the same tone? or would it sound more like a siren? i hope you get what im saying here

yes it will be the same tone just louder and it will honk but it may not honk for long with a flasher.you can set most alarns to horn honk setting or pulsed output and you will not need flasher.
