My 2015 F350 diesel comes with 2 batteries, not sure how they are connected, so to connect winch to only 1 or run cable to both? Max draw about 400A.What says the gurus. Frank.
Getting ready to do the wiring as hoping to have winch next week. My Ford workshop recommended that I only run the 02 active to rear and use chassis as ground , while also adding larger ground from each battery to chassis, what do you think. Thanks Frank.
