I thought I would add to the collective community knowledge and post up my completed dual battery system with a secondary electronics system. I basically wanted everything that is factory to run off the factory Main battery and I wanted all the do-dads that I have added to run off the second battery. Isolation is through the ever popular Blue Sea ML-ACR and I used their breakers, fuse blocks, ground buses throughout.
It is a relatively simple system and has been done before but this one is mine.

Awesome cable sourced from my local recycle facility for $2/pound!
