I know for jump starting a vehicle with two batteries you always jump from the main battery and main negative. So, my best guess would be the same for running accessories. One of the batteries should be connected to the main positive or the one going to the starter. (this would be the one to run accessories off of). Have to trace the wires but find the battery that runs cables from itself to the other battery directly (this battery would be the secondary) the other battery would be the main battery.
Hope this makes since, and be my best guess.

It doesn't make any difference.
The dual batteries on a diesel are wired in parallel with heavy cables for maximum starting power.When you hear hoofbeats, look for horses not zebras.
