    Hi guys,
    Like the title says what do I need and where do I hook the cables up to? Thanks for all your help.

    Later,
    Jack

    Get a second batt tray.

    Hook up the new batt to your old batt.

    pos to pos / neg to neg and neg to ground.

    Get the new batt the same size as the other one or get two new batt the same size and rating.

    I use the wire from a set of good jumper cables to connect them together.

    If you do this should you put in a bigger alternator?

    No, and if you have the VYU snow plow prep, you already have it. GM has a second battery kit available which has everythung you need.

    Sorry, no. I knew a guy who used to work for the local Chevy dealer and he got it and installed it there over the weekend. Got a battery, tray, all the cables and some terminals. Everything ran $150 or so for parts. It all connected to the factory terminal with the red cap under the hood too. This makes sure it gets properly charged. It also isolates the secondary battery so they don't both go dead together if you overuse it or leave something on.

    :rolleyes: A isolated batt is for a camper.
    Using a batt isolator for plowing defeats the purpose of having two batts.
    Using a batt isolator will do nothing for your lights dimming, your plow moving slowly or the batt getting drained down.

    For plowing you want the two batteries connected directly to each other. NO isolator.

    I only use an isolator for the camper.......;l

    Just get the batt tray, a batt, fuse, cable, cable ends, And get a batt with both side and top terminals it will make life easer.
