to install the ymap version ´(the dlc version) you first need to download https://www.gta5-mods.com/tools/mapeditor-2-ymap-converter
when you have downloaded it you need to use openiv to drag it into Mods/update/64/dlcpacks  and drag the custom_maps file in there and then go into Mods/update/update.rpf/common/data and then left click on the dlc list and click on edit, /u need to turn edit mode on in openiv first)
when you are in the dlc list copy this text in <Item>dlcpacks:/custom_maps/</Item> and click on save then you are great to go.
