Much time searching for parts "put in a secure place" months ago Finally found the end-plugs for the Can bus that terminate the autopilot cables when the GSA-28's are not installed, and put them in place. (will be powering up the system before I get to installing the auto-pilot). Then re-populated the panel with LRU's I'd removed for safety. Will get the other end of the Can bus secured tomorrow by installing and connecting the magnetometer.
