I'll look at it, but 1999 was the last year of the old body and that was only the full size SUV's.

 

O2 simm problem fixed! The ones I should have bounght for my truck to make the pink wires line up between the connector & simm is part# 104049 (2001-2003 5.3). I tried swaping the pins on part# 104047, which is suppose to be the ones for my truck but the pink wires didn't line up, but it still didn't work. I then thought that I might have damaged the simm so I bought part# 104049 & it didn't work either. Called casper electronics & they said when I installed the incorrect ones on my truck that it would blow the O2 heater fuse. I replaced the blown fuse & installed the #104049 & they work.

 

All right,glad you got it fixed.Didnt know the o2s had a fuse,learn something new every day
