-How to install-
Add the .pak file to "TEKKEN 7\TekkenGame\Content\Paks\~mods" (create the "~mods" folder if you don't have it), launch the game and select Kuma's 2P color.
If you also want the option for him to have the helmet on, just go on customization and save his original outfit with the helmet. 
Enjoy :)
