4.1 Wire Harness Installation
All electrical connections, except for the antenna(s) and shield grounds, are made through the D-sub
connectors on the rear of the unit. The shield grounds terminate to the connector backshells.
For additional information:
• Refer to section 5 for rear connector pinout and descriptions of interface connections
• Refer to appendix D for interconnect diagrams
• Refer to section 3.12 for special tools
Give sufficient space for installation of cables and connectors. The installer supplies and assembles all
cables. Cable lengths are dependent upon the installation.
To install pins into connectors and build a wire harness:
1. Remove 0.17 inches of insulation from wires going to the connectors.
2. Put the wire into the pin and crimp with one of the recommended (or equivalent) crimping tools.
3. Put the pin into the connector housing location as specified by the interconnect drawings in
appendix D.
4. Gently pull on the wire to make sure the pin is properly engaged into the connector.
5. Route and attach the cable run from the GTX 3X5 to the other units. Refer to section 3.14.
