i bought the NW dual batt tray and not there kit.

i had a large batt isolator from warn and a solnoid from warn.

i hooked it up that the main batt only works the truck. and the second batt runs everything else. the isolator chages both batt at the same time. and the solnoid turn the second output off. i have a switch in the cab to turn it on and off as to stop any drain that there may be. and for when pluging things in and out.

i could take some pics if you need.
