Well, good thing I marked every wire I touched.
So just swap them then?
25-26, 26-25
28-29, 29-28
65-66, 66-65
68-69, 69-68.
If ^^THAT^^ is right then I'll get out there with coffee in hand and get it done. I drive my car with it the other way. I hope I didn't screw anything up.
Thanks for the replies so far, HVYMTL.

dr w, it's probably been in open loop this whole time, lol but it shouldn't hurt anything other than your plugs may have a healthy coat of carbon. I thought mine were pinned wrong but I just had a dead o2 on bank 2. I bet your car runs better after you're finished!!
No problem, man. Glad I could help. And genesis, you can still get the rears deleted. After the repin, your old front connectors are your rear connectors as so the PCM sees. It won't do anything other than turn on your CEL if you leave them there, though. The tune just deletes them so that having nothing in those connectors won't set a light

Well, I got it done, just like you said HVYMTL. Only took a minute this time.
FINALLY was able to go WOT with the new headers. HOLY ****!! This thing runs like a raped ape! The pull it has above 2500 is awesome!
Thanks for all those who contributed to this thread. Awesome stuff.

Awesome!
Came across this thread right after I lost an eBay auction for some O2 extensions! Wheeew never been so glad to lose an auction saved me $40 excellent write up man. Some new Pacesetter LT's will be installed on the 99 TA this weekend hope the pin swap goes well! Looks to be pretty straight forward! Thanks

I know it's an old thread but thought I would chime in again anyway. I did the pin swap when I put my new LT's on it was so simple and so effective. Thanks again for the info!

Wow, what a simple yet brilliant idea. I agree w/ everyone else, this should be more prevalent among the LT guys. I'm throwing a couple codes, all related to a bad front o2
sensor, and was just about to run to the store for a new one when I stumbled on this thread. My rears are already tuned out too. So, out to the garage I go....

So by doing this, you are turning the rear 02's into the fronts, and it's the fronts that you delete and tune out correct?
So everything is the same, you still get a tune to delete the rear 02's, but the rears just read as the fronts now that the pins are switched right?
I always thought the rear 02's were different, everyone was saying the rears were different sensors and weren't capable of reading everything the fronts were.. hmm they were wrong lol
If this is true and works on my 97 z28 I'm about to cancel the order for the 02 extensions I just bought! I'm a wiring noob and it looks complicated, is it really that easy?

The biggest question I have about doing this is, do the 02's switch faster like they should compared running the long corvette 02's?
I know that 02's switch slower in headers but I didn't know if it was because of the lack of heat or the long *** wire going to the sensor.
Thanks.
