2012 Seneca RB Wiring

I am trying to clean up the battery compartment on the 2012 Seneca we bought. Someone has been in there working because I have wires bypassed and some cut. I would like to find a wiring diagram mainly for the 12V system.
There is a lot of corrosion and rusty terminals. If anyone has a 12V diagram I would certainly appreciate a copy.
Thanks All,
George

Take a look at these. From my 2014TS but yours is likely similar. The one picture is mine after I got rid of all the problematic glass inline fuses and Jayco's crimped connections that were all corroding.

Seneca battery area

Thanks Robby,
I have 4-12V batteries on my tray all wired in Parallel.
The drawing shows a 5th chassis battery do you have that?
Maybe they are not using the emergency start switch?
Let me know your thoughts please.
George

Our units have two chassis batteries under the cab, is that what you were referring to?
