First off the truck is running really good but I do have a few questions.

On the old 4.8l out of the 02 there was a plug on the right side of the oil pan, kind of by the starter, there is not plug on the 08 ls2, does anyone know what that might be?

And also if im not mistaken the oil pressure sending unit is about the oil filter on the 02 4.8 right? Well there is not place for it on the LS2, and the oil pressure gauge isnt working. Anyone have any ideas?
