With the white plastic, screwed into block near top of bellhousing. This was on a 1999 3.0.

oil pressure? with no pic this is an educated guess.
pass side? right next to the head? singe electrical post?

edit: oops, newer oil sensors have the big plastic connector thingie in your picture.

that is for sure the oil pressure sensor.

Behind passenger side head on the block, would be 3.0l Vulcan's oil pressure sensor
