Cadillac SRX Camshaft Camshaft Sensor Location

I Understand This Motor Has Bank 1 And Bank 2 And, On Each Bank, Has Sensor A And B. So, Is Bank One On The Left Or Right When Looking At...

Where Is The Camshaft Position B Sensor? Do You Have A Photo Of Its Location? Is It Fairly Easy To Replace? This Srx Has A 4.6l Engine.
