Here I am choosing the placement of the siren, I've made sure it is a spot that can't be accessed without opening the bonnet and also that it is far enough away from any heat sources like the exhaust. After you've placed the siren you'll need to have a hole through the firewall to plug the wires from the siren into the wiring harness from the alarm. Generally though I recommend leaving the siren until the last thing to plug in, you can tell from the dash light when the alarm is active or activated. If you want to test the car with the siren in you can also stuff it full of rags to muffle it quite effectively.
