A123 7s3p 60Ah modules from Fisker Karma - prompt for CAN messages?

I have some modules from a Fisker Karma with the OEM harness. I have figured out how to boot them up and which pins are CANH/CANL. The OEM harness relies on the module PCBs to jump each signal to the next module.

Trying to repurpose some code from MIT EVT, who used some similar modules for an EV project.

However, I don't think I have the CAN messages right. The Fisker modules are slightly different from the ones from that git repo, and I imagine the firmware on the PCBs is as well.

Has anyone cracked the A123 modules from the Fisker Karma?

Goal is to poll for cell voltages, temperatures, tell them to balance.
