maybe not so lenthy...it took me a while to do but wasn't too bad. i'm glad i borrowed a o2 socket set from o'reilly because it has offset sockets which make it a bit easier. i've read that the old ones (mine were original) seize up but they came out very easily without any pb blaster.new ones were cheap ntk (or maybe not since they didn't have anything stamped on them) universals from ebay and came with butt connectors already crimped onto the ends of wires.

the harness connectors for o2's - front one is on the right front side of the vc, the rear one is just above the timing chain cover in the rear - both are a gray plug with 2 white and one black wire.

i'll find out if i got the wires connected in about a week when i hook my laptop up again to check for codes, since i erased the ones i had and cleared the self learn.

the wires on the o2 are in a triangle and the 2 whites can be on top and the black one on the bottom - then when the plug is lying down and the clip is facing up the wires are alligned correctly.

in the meantime the car is running fine so i think i got everythng right. sorry for lackof pics but i had to rush before going to work.

connector with clip facing up white black whitecorresponding wires when 2 whites are up top and black bellow white white blackhope this helps if someone isn't sure.

btw it's recommended to solder the wires instead of using connectors but it was impossible. idk what kind of wire this was but they would not hold solder.
