With the Wiring Harness Tray now extended to give room for the all the wiring plus the Dynon modules it was a quick and simple task to install the three modules: ADAHRS, EMS, BAT. I paid particular attention to the Dynon manual for the installation of the ADAHRS module which specified brass mounting hardware and the need to be able to make adjustments to have it level in level flight. I should note that I used a photo that I got off the users' forum that purported to be of the Progressive Aerodyne's specialist, Angel, to guide me in all my adjustments to the the tray and the layout of the modules and to plan how I will 'clean up' all the wiring in the future.
