Anyone w/ Dual Batteries

    I'm changing the setup on my '97 K2500 to Dual Yellow Tops (w/ side & top Posts)
    & a 200amp Alt.
    Have a Salt Dogg to be installed next week (Bye Bye SpeedCaster!)
    I've read every Dual Battery post on the site - still have one question for those experienced
    Here's my plan
    Batteries in Parallel - no ISO
    all 1 AWG inc. Alt & starter leads
    triple grounded (engine, frame & body) = overkill- I know
    Question: Does it matter (wired in parallel) what's hooked up to which battery?
    i.e.: Orig. Battery location (fnt pass side) is a short run to the starter & Alt.
    but the solenoid for the Boss V (& I assume the harness run for the Salt Dogg) is on the
    drivers side - a nice short run to the second battery.
    Any thoughts on why I should or shouldn't set it up this way?
    Thanks in advance for any advise

    If they are wired in parallel without an isolator it will not make any difference what is hooked to either battery.

    And short runs are always better. Keep it that way.

    Keep the runs short, and you will be ok. With no Isolator, YOu should be able to hook to either battery, without failure..
