BCM/etc data requested- tracking down parasitic drain

Hello everyone!

I've been poking about the forums for a bit looking for resources to help me with my latest adoptions:

They were (and still somewhat are) physically beat, but were mostly kept up mechanically. One of them has backseats (now), the other, I'm looking for a better donor, since it's in much better condition internally (minus the headliner).

They both need to have the ignition switch recall done, but I'll need to get a rolling permit for them in order for that.. which brings me to my question:

I've been trying to track down a parasitic draw on BOTH cars. I've eyeballed the few things that were connected to the positive terminal, and it appears that only stock connectors are left (I've removed the useless clipped cables for the aftermarket stuff which was removed), so.. it's obviously something else.

I'm wondering if anyone has BCM data so I know how long I have between opening the car, and it going back to idle/et al. I plan on doing a check on all fuses to try to find the culprit, but I'm flying blind- these are my newest GMs.

I do have access to a Tech 2- that helped me isolate and replace the ABS sensor issue on the one shown on the left.

I'd really like to get these out on the road- the 3.9L is amazingly peppy, even if it is a little thirsty.
