ready brake install on 2011 jeep grand cherokee

I am in the process of installing a ready brake cable install on my 2011 jeep grand cherokee. I understand this model year is a little different as it has a double firewall. Install videos on this year seem to be far and few between. My local NSA product dealer will not help me because I did not purchase it through them. Any help on would be appreciated. One old thread from 2011 had pics, but for some reason I cant get the pics to load. thank you
