If you're talking about the mod (zip) files, which I think you are. You need to put them into your mods directory. Note: do not unzip them unless specifically instructed to do so.
Then when you run the game you should go into your extras menu and switch the mods on.
Lastly make sure you have upgraded your game to the version F14.6 otherwise you'll not be able to do this.
Also make sure you read instructions as to any other configuration changes you may have to implement to get the mods working. You can do this by viewing the zip files with WinZip or another zip compliant package, and opening any readme files.
