In OpenIV navigate to \mods\update\update.rpf\common\data and extract dlclist.xml to your desktop. Open it with notepad and add the text below to the list of dlcpacks, save it and move it back where it came from. 
	<Item>dlcpacks:\2015polstang\</Item>

Then navigate to \mods\update\x64\dlcpacks and create a new folder called 2015polstang and put my dlc.rpf into it. 


Use trainer to spawn by name: 2015polstang

OPTIONAL - BACKUP CARCOLS FIRST - To use my custom siren pattern just place my carcols in \mods\update\update.rpf\x64\data but please note, my carcols affects all police cars that use siren1 pattern and I do have flashing headlights and taillights enabled!
