    Well it seems I am following Barlowrs on his ideas so thanks to him but here is my Columbia Overland and National Luna with aux fuse block install.
    I had installed this kit about a year ago but I was never happy with how the wiring was organized or where the aux fuse block was installed so I set out to fix it. I ordered so braided sleeving and heat shrink, went to West Marine for the cables and connectors and had a aluminum plate made up for the fuse block. I ended up having to splice the cable going from the engine to the battery so it would reach and look clean. Took my time and it turned out even better than I thought.

    Why would you need a second battery?

    Second battery powers ARB frig, 12v to bed, gps, and any future 12v needs. Also a bit of piece of mind can use second battery to jumpstart primary battery in the event that it goes dead.

    That's awesome! Whoa, you're in the Seattle area too!! Hmmm, I've been wanting to do a dual battery setup but was reluctant since I wasn't too familiar on the wiring. Wanna help? :p

    Great looking install, very clean and professional looking.

    What model Taco do you have?

    I have an 06 TRD Off Road with an 130A alternator and was wondering if the Nat'l Luna kit would work with it.

    Very nice installation.
    As an alternative in a DC, especially if loads are in cab or bed, is to put a thin, taller AGM battery with an intelligent combiner/isolator behind the rear passenger side seatback. Very easy installation. Also easy to install inverter behind rear driver side seatback, with extra 12v outlets.
    As OP suggested, use Blue Sea components, easily available at West Marine. They are good quality and have excellent tech support.
    My primary reason for installing a second battery is that we are often parked for hours with VHF radio on, 12v spotlight, 110v halogen work light, chargers for handheld radio, phones and sat phone, etc. - and don't want to wear down engine battery!
    Good luck.

    Very very clean install

    just out of curiosity did you change the alternator to handle the load of the extra battery?

    WOW...very nicely executed. I appreciate the step-by-step and the sources for all the components. I'll probably mimic all you've done and end up with a very similar system.
