***UPDATED TO USE THE GRAA MODPACK VERSION 3.0***

To use this GRAA mod with the ECP mod, you need to do the following  EXACTLY

Take the Config.cpp that is in this folder "ECP config" of the file you are currently reading
Put this Config.cpp in ...\your OFP install folder\@ECP\Bin\

basically replace the Config.cpp found in the bin folder of the ECP mod by this new one.
But i more than STRONGLY recommend to back up the original ECP config first just in case.

Once done, take ALL the pbo from the Addons folder of the GRAA mod
Then put them in the Addons folder of the ECP mod, if you already have GRAA verson 2 pbo in there , overwrite them as they are outdated 
Now  take the file Anim.pbo (not anims.pbo they are not the same) located in the Dta folder of the GRAA mod folder and put it in the Dta folder of the ECP mod folder.

Once done, you can now edit the new config.cpp to enable or disable the various GRAA options to your liking.
Then just launch OFP with the mod ECP and play.
(i strongly suggest you DO NOT use another mod while playing with this config in ECP) 

NOTE : 
1  -  YOU must have already installed the --latest version--- of the ECP mod correctly before

2  -  This config do not all of the numerous GRAA options to be enabled/disabled in the Config.cpp , as i think more of them could conflict with ECP
