Hello. Just joined and happy to be here. I am trying to install a back up camera in my 07 Liberty but cant figure out which wire is for the reverse circuit. I saw some posts about this but not really resolved. Does anyone know? I would assume others have added these cameras, as well. I saw a post by Billwill mentioning the wiring diagrams for the 07 were impossible to find. I wonder why that is. Is there something special about that year / Model? Any help is much appreciated!!
