i had EVAP and rear o2s tuned out so im just running 2 front upstream o2s/ Im ready to order them on Rockauto but im confused as to if this is the correct one. my harness came from a 2000 tahoe and the o2 connectors are white square shaped with a 4 pin harness. like the first picture below...the second pic is the one on rockauto but they have it listed as upstream and downstream... the reason i want to order from there is because the price is WAYYYYY better than what the local parts store wants to charge.

this is how my O2 connector looks ( 1st pic)

this is rock autos ( says upstream & downstream)

Ls1 I don't think there the right ones. Compare them with Bosch 13111. Those will fit the long tubes.

im just running shorties.. why would they have it listed as both ( downstream and upstream?) is there a visual difference between the two?

the wire length is the ONLY difference between all the PNs
