I just got my avionics kit today for the Dynon D1000/HDX1100. The plans I got from Van's starts with section -42C. Looking at the first few steps, the sequence has you connecting the Engine monitor and the Battery backup to the AV-50000A module that has somehow already been magically installed. Am I missing a assembly section before -42C that installs this stuff? I can't find any info on the Van's website and -42C was the first section that was included with my avionics kit.....
