Recommend to open the KeyboardConfig.ini to adjust the key binds and match them with your ELS or DLS config file.


VehicleSirenSetup.xml - Smart Controller Series B (Police)
CHPSetupsUI.xml - Whelen CenCom Carbide (CHP)

if you have vehicle models with different names just replace the name model to your current ones.
if you want to add the Whelen for CHP or any other vehicle go to SirenMastery\UI\CHP\CHPSetupsUI.xml
if you want to add the Smart Controller Series B for Police or any other vehicle go to SirenMastery\VehicleSirenSetup.xml


Sorry for so much confusion the plugin should work as expected now. (the crowd is going crazy omg)
