New to this system..."second order configuration"?
power on the system while holding the [menu] key until you see "Configuration Mode" displayed. Then touch the icon labeled "Engine & Airframe", in the sub menus here you will specify the type of sensors attached to the various inputs on the GEA 24, GAD 27. See the installation manual, section 30.
The configuration settings can be downloaded directly from the Vans web site on to a SD card and uploaded into the G3x touch.
Job done!.

UPDATE: I found the EMS B/U battery switch to be defective. This is a DPST switch with 8 terminal spades, 7 of which are used. A continuity check of all terminal combinations with the switch on and off showed continuity between only 2 of the terminals so I replaced it through Mouser (exact match, still waiting for one from Van's). I got different results between the original and the replacement, albeit still fewer terminals connected than I expected. The switch is sealed and I wonder if it is more that simple mechanical switch??? I replaced the original and now, when I turn the EMS switch on the G3X reads the engine probe, the fuel pumps work, the Lane LEDS light up for a while and the Rotax fuse box LEDS stay lit . The 'ECU Failed" warning goes out but the "Check ECS" light stays on. Based on one prior conversation with Van's Support, I ordered a new HIC module 12 days ago per their admitted guess at solving the problem. I still have not received the order although the items are supposed to be in stock. Prior to replacing the EMS switch, I spoke to three of Van's support staff (two of which never got back to me after promising to do so) about the issue. None of them seem to have a clue for a fix. For the first time in years I'm questioning their labeling of "Our awesome builder support team". ANY SUGGESTIONS (OR EVEN GUESSES) APPRECIATED
Initially I did not turn on the EMS batt, however, I got NO engine info at all. I later tried the EMS switch and it blew the fuse. I replace the fuse and tried it again. It did not blow the fuse again but still no response. I later replaced teh EMS batt switch after discovering very limited continuity amongst its termonals. The system (the Rotax fusebox) now powers up on the EMS battery but still not on just the main switch.
PROBLEM SOLVED: As recorded above, I ordered a new EMS B/U BATTERY switch and HIC module. Replacing the switch did not cure any of the problems, however, it was definitely bad based on lack of continuity between all but two of the spade terminals. I then removed the HIC module and discovered a small burnt spot on the rear of the circuit board. Installing the new HIC module solved the problem of the Garmin not recognizing the Rotax engine and eliminated the "ECU FAILED" warning light. The "CHECK ECS" warning light was eliminated by disabling the GAD 27 in the Garmin configuration after reading a post saying to do so if you do not have a GAD 72. All systems APPEAR to be workiong properly now. I will know for sure when I start the engine the first time.
