Oil pressure sending unit location??

I currently have a 2016 2500 Sprinter with the 2.1 liter OM 651 engine.  I am trying to install the Frantz oil filter system to the engine but I cannot find a picture or location where I can tap into a high pressure oil line from the engine, oil pressure sending unit or pressure sensor, and then where to plumb in the return line from the bypass filter system back to the engine.  I do not want to tap into the oil pan with a fitting. 

Any pictures or suggestions would be a great help!!  Thanks.
