Jeep Grand Cherokee Laredo Starter Replace/Remove

I Just Bought A New Starter And Got It All Put In And The Old One Out Etc. Anyways I'm Having Trouble When I Go To Attach The Negative...

Where Is The Starter And Can You Show A Picture Of Where Its At In The Engine

How Long Does A Starter Usually Last? We Replaced Ours In July 07 With A Jeep Part. Car Is Now Acting Like It Might Need A New One....

My Started And Alternator Was Tested Good Sunday At Auto Zone But Now My Jeep Will Not Start Without Tapping Starter And Key In Ignition....
