first of all, do you have a siren output or light output in that alarm system?. does the lights flash once to arm or to disarm, only then i can provide you the information onto how to wire it with a relay.

There's a diagram posted on this site under the relay section for horn honk options

on most alarm harneses its the BROWN / white wire. most are -neg. and will need a relay.

connect BROWN / white to terminal 85, connect relay terminals 86 & 87 to +12v constant power. connect terminal 30 to your horn wire.

if your horn wire is -neg then just use your BROWN / white wire. use a probe to find out

or you can use directed web site for a print out of your wiring and locations of the wiring to find out.

This is a highly inaccurate statement. There are many alarms that don't offer offer a horn honk output.

you can use the light output, the siren output and the central locking wires (negative switching output using diodes but with all these, you will have to use a relay to drive the hight current to the horn honk.

hope this helps
