1) Depending on the alarm, there should be an output for the horn.

2)Depending on the vehicle, the horn may be positive switche or ground switched. Use a DMM to check wire.

3) Check the output wire on the alarm, usually if it is ground switched you will not need a relay. this is not in all cases. It is alarm dependent.
