NOTE: If desired, the power wire may be spliced to an unswitched power source in a
manner acceptable to the aircraft manufacturer, or as described in AC 43.13-1,
Paragraph 11-167.
11)
Crimp female terminal pins (151-6628) to the cockpit remote switch end, as follows:
NOTE: Use Molex crimp tool 63811-3300, or an equivalent tool for 0.062 in. terminal pins.
a)
Each harness wire.
b)
Remote switch ground wire.
c)
Remote switch power wire.
12)
Bundle the wiring into a complete harness, with breakouts as appropriate, such that the wiring can be
properly supported and attached to the airframe. Refer to the aircraft manufacturer’s written
instructions or AC 43.13-1, Chapter 11, § 9 through 12, as applicable.

ELT D-Sub Plug Installation
NOTE:
Artex supplies a DB15 female solder contact connector with all ME406 ELT kits. If a crimp
contact connector is preferred, it is acceptable to purchase and use an alternate DB15 crimp
contact connector. Ensure it conforms to MIL-C-24308 or other commercial specification to
ensure performance requirements are met.
NOTE:
If moisture intrusion is a possibility, seal the back side of the connector. See SUBTASK
25-62-30-450-003 on page 57.
1)
Select a rubber grommet, supplied as part of the D-Sub housing kit (150-1127), that fits snugly around
the harness wiring.
2)
Feed the wiring harness, ground wire, and buzzer power wire through the rubber grommet, such that
the raised collar end of the grommet fits inside the housing. See Figure 22 D-Sub Plug Assembly on page
57.
NOTE:
For composite airframe installations, the buzzer ground wire should also be routed
through the grommet.
3)
Slide the grommet away from the cable and other conductor ends, such that it does not interfere with
soldering the conductors to the plug (150-1130).
4)
Solder the buzzer ground conductor to the cable shield or ground conductor for composite airframe
installations. See Figure 20 Composite Airframe Wiring Diagrams on page 54.
5)
Fabricate a short jumper wire, approximately 1.5 in. (38 mm) long.
CAUTION: THE ELT WILL NOT AUTOMATICALLY ACTIVATE IF THE JUMPER (G-SWITCH
LOOP) IS NOT PROPERLY INSTALLED IN THE ELT D-SUB CONNECTOR.
a)
Strip approximately 0.15 in. (3 mm) of insulation from both ends of each of the wire.
b)
Dress and tin the bare wire ends to prevent the strands from fraying during terminal crimping
operations.
c)
Solder the jumper wire to D-Sub pins 5 and 12.
6)
Solder the wiring to the D-Sub plug as follows, referring to the wiring diagram appropriate for the
installation:
a)
Harness wires,
NOTE: Make note of the wiring identification and pin location relationships, such that the
wiring at the remote switch end can be terminated correctly.
b)
Buzzer power wire, and
c)
Ground wire.
