Swapped PCM pins for O2's... Is it right?
 
Hey guys, need assurance....

I installed TSP headers and Y about 3 weeks ago. I followed this write-up, LT Header Guys!!! No more extensions or corvette o2s!

I just want some reassurace that I did it right, b/c initially I did it WRONG.

I swapped as follows:

25+26
28+29
65+66
68+69

For example, 25 wire is now plugged into 26 port, 26 wire into 25 port; etc.

I'm pretty sure it's right now, but since I still havent gotten tuned, I still have the SES light and just feel uneasy about it. I deleted air and went with an 04+ LS6 valley all at the same time, so it was kinda a lot all at once.

Thanks for the replies in advance guys. Like I said, i just want to make sure I repinned the connections correctly to swap my front and rear O2's

wow first I have seen that thread... seems like if you pinned it out right then no problem... ses light will be from the computer not reading anything on bank 1/2 sensor 2s... then you got rid of your air,egr, and emission stuff.... if its running right then its good... if you have a scan tool you can check your O2 sensor voltages and see if they are working?

I guess all there is to do is scan it.

I just wish the thread would say, "Swap this # with this wire..."

Car is running good, I can tell he needs a tune though.

I'm not worried about the lights. I knew I'd have them due to the air and all, just wanted to be sure my o2's were good though.
