where is the egr valve located on 08 jeep wrangler sahara

The EGR valve is on the passenger side of the engine back near the firewall. I was told to replace it on mine that removing the Battery, Battery Tray and Fusebox would make accessing it much easier. The Dealer and local repair shops were going to charge me @$125 for just the valve itself. I went on Amazon and found one for only $90: http://www.amazon.com/gp/product/B00FZMGF20/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1 Since I saved that much money by buying the exact Mopar part I needed, I'm going to attempt the repair myself also.
