Installation ProcedureGDL 69/69A Installation Manual Page 2-5190-00355-02 Revision E2.5 Cabling and WiringWiring should be installed in accordance with AC 43.13-1B Chapter 11. When wire separation cannot beachieved, the following issues should be addressed:• The cable harness should not be located near flight control cables and control, high electricalcapacity lines or fuel lines• The cable harness should be located in a protected area of the aircraft• Do not route cable near high-energy sourcesRefer to the interconnection diagrams in Appendix D for the appropriate wiring. Once the cableassemblies have been made, attach the cable connector to the rear of the rack. Route the wiring bundle asappropriate. Use 22 or 24 AWG wire for all connections except for power. Use 22 AWG forpower/ground. Avoid sharp bends.After the cable assemblies are made assemble the backshell as shown in Figure 2-6. Then install thebackshell connector to the rear plate using the screws provided in the connector kit. After the rack isinstalled, assemble the rear plate into the rack.2.5.1 Wiring HarnessAllow adequate space for installation of cables and connectors. The installer supplies and fabricates all ofthe cables. Except for the antenna connection, all electrical connections are made through a 78-pin D-Subminiature connector provided by Garmin. Construct the wiring harness according to the informationcontained in this and the following sections. Cable lengths will vary depending upon installation. Stripall wires going to the 78-pin D-Sub connector 1/8”. Insert the wire into the pin and crimp with one of therecommended (or equivalent) crimping tools. Insert the pin into the 78-pin D-Sub connector housinglocation as specified by the interconnect drawing in Appendix D. Verify the pin is properly engaged intothe connector by gently tugging on the wire. Route and secure the cable run from the GDL 69/69A to theother units away from sources of electrical noise.Section 3 defines the electrical characteristics of all input and output signals. Required connectors andassociated hardware are supplied with the connector kit. See Appendix D for interconnect wiringdiagrams.CAUTIONCheck wiring connections for errors before inserting the GDL 69/69Ainto the rack or mounting bracket. Incorrect wiring could causecomponent damage.Table 2-2.
