i'll have to look, i have several o2 sensors i think... 3rd gen fbodies are 1 wire iirc.

EDIT:
ok, i crawled under the truck. the yukon has a 4 wire O2 sensor, (had to since the one code says "heated", lol) Ls1 O2s are also 4 wire so i pulled it from the yukon to compare it to the LS1 ones. One problem.. all is the same, except for the connector. the yukon has a female end, ls1 has a male end... well one ls1 O2 i have had the wire end dragging sinc ei had O2 sims installed, and the connector was worn down. since i cant sell it like that, i cut off the connector from the yukon O2 and spliced the female connector to the ls1 O2. I just reinstalled it. i cleared the codes before and so far nothing again. i dont care if p0141 coems up cause it wont set the SES which i failed for(even though apparently my SES dash bulb is burnt out(or was removed). Also i read that WOT can cause those codes to appear faster, lol. so until the pcm is ready for inspection, i will be babying the truck and not putting my foot to the floor, i figure it cant hurt lol.
