Backshell Assemblies
Connector kits include backshell assemblies. The backshell assembly houses the configuration module
and a thermocouple reference junction (if applicable). 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 (190-00313-11), Configuration Module (190-00313-10), and
Thermocouple (190-00313-01) can be downloaded from the Dealer portion of the Garmin website
