2004 Vortec 5.3 Oil Pressure Sending Unit?

I suspect my oil pressure sending unit may be going crazy, so want to replace it. First, since I don't have any service manuals, I need to know where the unit is.

It's a 5.3 LS style (Vortec) gas engine in a 2004 Silverado 1500 4WD.

Anyone got a photo? Or link to a shop manual?

Thanks, LBJ
