get the minn kota power station. less wiring to have to do, built in manual breaker, battery meter, and 2 12 volt accessory plugs. i'd recommend it for the beaver fever mod.
based on the simple wiring i had done one of those plugs will act as the back up for the livewell since the power plug is cigarette lighter style
