Completed the EMS-220 support. Test fit the support behind the ignition component support on the channel. Fastened with sheet metal screws. Found that the EMS-220 support had too much side to side flex. Fabricated and installed a diagonal brace across the rear opening of the support. That fixed the flex problem. Put Tinnerman nuts on the channel piece flanges for permanent installation of the EMS-220 support using #8 x 3/8 SS sheet metal screws. Mounted the EMS-220 module to the top shelf of the support. Dressed the DYnon network cable for connection between the EMS-220 and the Dynon unit.
