Was ist da die Koordinate ???

Hey Leute ich habe hier so ein filterscript gefunden und möchte die Sirene auf einen Krankenwagen und so setzen da würde ich gerne wissen was die [x] [y] [z] Koordinate sind.

else if(GetVehicleModel(tmpcar) == 416)
{
sirene[GetPlayerVehicleID(playerid)] = CreateObject(19288,0,0,0,0,0,0,100);
sirene1[GetPlayerVehicleID(playerid)] = CreateObject(19419,0,0,0,0,0,0,100);
sirene2[GetPlayerVehicleID(playerid)] = CreateObject(19288,0,0,0,0,0,0,100);
sirene3[GetPlayerVehicleID(playerid)] = CreateObject(19288,0,0,0,0,0,0,100);
AttachObjectToVehicle(sirene[GetPlayerVehicleID(playerid)],GetPlayerVehicleID(playerid),0.0,2.6,0,0,0,0);//Vorne Mitte
AttachObjectToVehicle(sirene1[GetPlayerVehicleID(playerid)],GetPlayerVehicleID(playerid),00.0,0.0,0.6,0,0,0);//Dach sirene
AttachObjectToVehicle(sirene2[GetPlayerVehicleID(playerid)],GetPlayerVehicleID(playerid),0.7,2.6,0,0,0,0);//Vorne Licht Beifahrerseite
AttachObjectToVehicle(sirene3[GetPlayerVehicleID(playerid)],GetPlayerVehicleID(playerid),-0.7,2.6,0,0,0,0);//Vorne Licht Fahrerseite
UCL[GetPlayerVehicleID(playerid)] = 1;
SendClientMessage(playerid,0xFF0000,"Blaulicht eingeschalten!");
return 1;
}

Und welche zahlen muss ich da jetzt genau ändern ??
