Garmin GTX 33 Installation Manual - Page 32

3.2 Wiring Harness Installation Allow adequate space for installation of cables and connectors. The installer shall supply and fabricate all cables. All electrical connections to the GTX 33 are made through one 62-pin D-subminiature connector. Section 4 defines the electrical characteristics of all input and output signals. Required connectors and associated hardware are supplied with the connector kit. See Appendix D for examples of interconnect wiring diagrams. Construct the actual harnesses in accordance with the aircraft manufacturer authorized interconnect standards. CAUTION Check wiring connections for errors before inserting the GTX 33 into the rack. Incorrect wiring could cause internal component damage. Table 3-1.

Non-Garmin part numbers shown are not maintained by Garmin and consequently are subject to change without notice. 2. Extracting the 18 AWG contacts 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.
