The OAT sensor attaches to the GAD 58 unit in G3X package. I’ve got an Astore, 2016, and have no schematic or wiring diagram that shows the locations of the different elements of the system as installed in my airplane. Since my OAT and TAS have failed, my Garmin Avionics shop would like this information instead of taking the airplane apart to find it. Can anyone help me on this?

From the G3x install manual:
2.1.1.4 Outside Air Temperature
The outside air temperature (OAT) probe used in the G3X system is the GTP 59. A minimum of one OAT probe is required, and is connected to the #1 ADAHRS. In an installation with multiple ADAHRS units, air temperature data is shared via the CAN bus. Additional OAT probes may be connected to the other ADAHRS LRUs for redundancy, although this is not commonly done. Refer to Section 21 for GTP 59 installation information.
Page 58 of the Tecnam Astore maintenance manual shows the physical location of the ADAHRS. The G3X install manual has schematics.
