    Hi, I am wiring a dual battery into my engine bay. I could really use some advice.
    What is the best way to do this in order to reduce the amount of wiring that is needed?

    Objective:
    • I need to connect the 2 batteries together with the ML-ACR.
    • I also need to run a large power cable from the Aux Battery through the drivers side firewall. The wire going through firewall will connect to a fuse box in the cab and one in the bed.
    Wiring Plan:


    Questions:
    Edit:
    250 amp bus bar would not be enough for the self jump start scenario.
    I am thinking this 600 amp bus bar would be though.

    And on the subject of the self jump:
    If I wire it like the diagram, am I putting my auxiliary fuse boxes at risk since they would be connected to the Bus Bar?

    Blue Sea offers the following wiring diagram that details how to connect the batteries to the ML-ACR and accessories. This is what I recommend.

    I would not use busbars between the batteries and the ACR. Instead, if you feel you need a busbar, then I would run a separate cable from the aux battery to the busbar and then branch out from there.

    Definitely connect your winch to your starter battery!

    I appreciate your input. Essentially, I was just trying to figure out an alternative setup that would allow me to run less wire.
    I am know thinking any deviation from the normal setup is just asking for issues.

    edit:
    Actually, it looks like just one more large power wire.

    What hasn't been modified?
    I think you wound be fine connecting them at a bus bar. I’d make sure that the wire to the ml-acr and the battery be touching, then bolted to the busbar. That way it’s most possible contact.
