use the pulse from the siren and the pulse of negative parking light to activate a relay coil then interface the horn between 30 and 87 pins of relay (use 2n2222 to invert parking light pulse from alarm.)

In order to inform you in a accurate way tell us the make and model of your vehicule and alarm
