OK I got that already

PCM is in the bottom of the air box.
Thanks

BCM (body control module) is above the parking brake (well, it is on my Impala).
I was looking at that yesterday, thinking it might be the PCM because its about the same size as the old OBDI. Im wondering how to pull it out of there to get better access to the plugs, its tight, there are other units under there as well ???

EBCM (electronic brake control module) is attached to the ABS modulator, in the vicinity of the driver side strut tower.
OK, Thanks!... I agree, I'd rather unplug these things due to what I've heard called "stray voltage". I screwed up the ign. module on my old Cierra welding the exhaust. I dont want to take chances with this more complicated, expensive, advanced system. I'm mig welding a few patched by strut towers and new rocker panels, a few other spots as well. PITA... but its a great sound car otherwise.
