I assume it is the old style with a 350 (5.7) since I believe the new style was in 2000 for Tahoes. With that being said the drivers side from front to rear are 1,3,5 and 7 in that order and the passenger side from front to rear is 2,4,6 and 8 in that order. So the answere to your question is the 2nd cylinder back on the passenger side is the number 4 cylinder.
