NOTES
1.
Non-Garmin part numbers shown are not maintained by Garmin and consequently are subject
to change without notice.
2.
Extracting the #16, #18 and #20 contact requires that the expanded wire barrel be cut off from
the contact. It may also be necessary to push the pin out from the face of the connector when
using an extractor due to the absence of the wire. A new contact must be used when
reassembling the connector.
3.3 Backshell Assembly and D-Subminiature Connectors
The GWX 68 connector kit (011-01114-00) includes one Garmin backshell assembly. Garmin’s
backshell connectors give the installer the ability to quickly and easily terminate shield grounds at the
backshell housing using the Shield Block ground kit. The term ‘D-Sub’ (D-Subminiature) connectors
have a letter “D” physical shape. D-Sub refers only to the polarized shell that holds the contacts (pins or
sockets) in place. Table 3-3 lists Garmin part numbers for the GWX 68 D-Sub Connectors and the
Backshell Assembly.
