    there is relay and two fuses in fuse panel. D12D Power relay is actuated with VECU, ECM ign. runs from Ign relay in fuse box.
    No hidden bat. power fuses like with Cummins

    Check cables to the batteries first, tighten them. My truck always starts acting funny when they get loose.

    Batteries all tigh grounds look fine as well. Truck runs fine just no spedometer or display in little window in center. Where is the ecm located and could it have come unplugged to to dash?
