a 2009 is going to be vastly different. Interior was changed in 2011, Engine was changed in 2012.
What specifically are you looking for? In 2012 jeeps basically went to fully modern electrics and even before that pretty much everything is controlled by the computer. No more changing out a gear to change the speedometer. An app is needed to make adjustments to settings. I'm unsure if there is a fully complete schematic out there out side of something available to dealers /mechs
The more info you give us, the better we can help.
