Garmin G3X Installation Manual page 26

1.7.4 Backshell Assemblies
Connector kits include backshell assemblies. The backshell assembly houses the configuration module
and a thermocouple reference junction (if applicable, see Appendix D). Garmin's backshell connectors
give the installer the ability to quickly and easily terminate shield grounds at the backshell housing. The
instructions needed to install the Jackscrew Backshell, Configuration Module, and Thermocouple are
located in Appendix B.
The GDU 37X rear connector (J3701) is electrically isolated. For installations using
shielded cables, a ground pin must be tied to the connector shell.
