Electrical Connections
All electrical connections, except for the antenna, are made through a single, 25 pin, D subminiature connector.
Figure 2-1 defines the electrical characteristics of all input and output signals and identifies the cable requirements
for each signal. Required connector and associated hardware are supplied in the installation kit
(P/N 010-10160-00). See figures B4 and B5 for interconnect wiring diagrams.
Larger pins are supplied for the connector to provide power and ground at pins 13, 14, 15, and 25 when required.
Refer to Figure B4, Note 3.

NOTES
1. Insertion/extraction tools from ITT Cannon are all plastic; others are plastic with metal tip.
2. Non-Garmin part numbers shown are not maintained by Garmin and consequently are subject to
change without notice.
3. Alternate contacts for 18 AWG wire: As an alternative to the Positronic contacts listed (and provided
in the installation kit), the installer may use contacts made by ITT Cannon under P/N 031-1007-001.
These contacts require the use of a different crimp tool positioner than shown in the table, with the part
numbers as follows: Daniels P/N K250, Astro P/N 616245, or ITT Cannon P/N 980-0005-722.
4. All wires must be passed through the backshell before being assembled to connector.
5. In aircraft equipped with a dropping resistor for +28 VDC buss voltage, make sure the dropping
resistor is bypassed.
