3.8 Cable Installation
Route the coaxial cable to the rack location keeping in mind the recommendations of Section 2.6.
Terminate the coax with the coax connectors following the manufacturer instructions. Secure the cable in
accordance with good aviation practice.
The card-edge connector may be used to terminate shield grounds to the 400W Series back plate.
Feed wires through the connector backshells before insertion into the 25-, 44-, and 78-pin connectors.
Contacts for the 25-, 44-, and 78-pin connectors must be crimped onto the individual wires of the aircraft
wiring harness. The following table lists contact part numbers (for reference). See Table 3-3 for
recommended crimp tools.

Notes:
1. Non-Garmin part numbers shown are not maintained by Garmin and consequently are subject to
change without notice.
2. 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.
3. For the card-edge connector pin contacts, use AMP part number 90272-1 or equivalent
crimping tool.
To prevent a possible short across the pins in the wiring harness, Teflon shrink tubing P/N 312-00005-05,
provided in Connector Kit 011-00351-00 (P4002) covers the oversized power and ground pin contacts
P/N 336-00023-00 (pins 11, 12, 21, 22) that protrude from the back of the connector shell. Before
crimping the pins onto the wire:
1. Cut the tubing (312-00005-05) into 4 equal lengths.
2. Slide a short piece of the tubing over the wire.
3. Strip the wire and crimp the pin (336-00023-00) onto the wire.
4. Insert the pin into the connector shell.
5. Slide the tubing over the exposed portion of the pin and shrink using a heat gun.
