1.5 MountingRefer to Section 2 and Section 3 for specific mounting instructions for each component of the GDU 37X,and to Appendix C for Outline & Installation Drawings.1.6 Wiring/Cabling ConsiderationsUse MIL-W-22759/16 (or other approved wire) AWG #24 or larger wire for all connections unlessotherwise specified. The standard pin contacts supplied in the connector kit are compatible with up toAWG #22 wire. In cases where some installations have more than one LRU sharing a common circuitbreaker, sizing and wire gauge is based on aircraft circuit breaker layout, length of wiring, current draw onunits, and internal unit protection characteristics. Do not attempt to combine more than one unit on thesame circuit breaker.RG400 or RG142 coaxial cable with 50 Ω nominal impedance and meeting applicable aviation regulationsshould be used for the installation.1.6.1 Wiring Harness InstallationAllow adequate space for installation of cables and connectors. Ensure that routing of the wiring does notcome in contact with sources of heat, RF or EMI interference. Analog Input wires routed too close tospark plugs, plug wires, or magnetos may result in erratic readings.The installer shall supply and fabricate all of the cables. The connector is available in the GDU 37XConnector Kit (011-01921-00). Electrical connections are made through D subminiature connectors for
