My 1st vats removal attempt

[S10223]

Good evening everyone,
First off, I'm a noob. I've been reading and watching videos for months, to prepare to start my LS swap and helping a friend do his.
We have the 03 and up PCM Blue/Green. I want to remove VATS, change the transmission type, I used a nv3500 and remove the rear O2 sensors.
Ive played around with a bin but never found where to remove the O2 stuff, if someone could also point me into that direction?

Looking and it seems ppl like the 7603 XDF. Will that be ok for me to use to read my bin.

My pcm : service#12586242. HDW#: 12583660

Thanks Jeff.
