Hello Again Everyone,
Brief background, I am adding a battery monitor so I can better gauge battery life and to avoid draining too low. I am heeding the advice of most here and bought a Victron BMV-712. Haven’t tried to install yet, just planning my wiring before I start. I am having some trouble because most videos and explanations I have found are for batteries wired in parallel but I have two 6v bats wired in series I think. Anyway, I’ve attached some pics with the existing setup and what I think the new setup should be. They are labeled in my own kind of way, sorry I’m not an engineer or knowledgeable of all the standard terminology.

Three things stand out, I’m not sure if what do with W1 or W4 which I think belong to the blue sea charge relay controller. I added my guess as to where they’ll go on the Victron instructions in blue lettering.
next I’ll need to buy a wire, any recommendations on gauge or type of wire?
Lastly, do I have the instructions labeled right for my ultimate end goal?
thanks in advance for any input.
