    My ute has keyless entry. When the you use the remote to lock the doors there is an accessory wire which becomes active, 12v. I would like to connect a self contained backup alarm siren to this. The siren has it's own trigger wires, but I would like it to run for maybe 30 seconds not just while the door is open. Any suggestions would be appreciated.

    Can you provide a schematic of the siren as it is currently configured?
