(7)
Prepare the wires fabricated in Step (6), as described in Steps (2)(a) and (2)(b).
(8)
Crimp appropriately sized ring terminals on the buzzer ends of the buzzer power and ground
wires.
(9)
Crimp an appropriately sized ring terminals on the airframe end of the ground wires.
(10) Crimp an appropriately sized ring terminal on the remote switch power source wire end.
NOTE:
(11) Crimp female terminal pins (151-6628) to the cockpit remote switch end, as follows:
NOTE:
(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
(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 21. D-Sub
Plug Assembly", on page 67.
NOTE:
(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 19. Composite Airframe Wiring Diagrams", on page 64.
(5)
Fabricate a short jumper wire, approximately 1.5 in. (38 mm) long.
CAUTION:
(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.

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.
Use Molex crimp tool 63811-3300, or an equivalent tool for 0.062 in. terminal pins.
For composite airframe installations, the buzzer ground wire should also be routed
through the grommet.
THE ELT WILL NOT AUTOMATICALLY ACTIVATE IF THE JUMPER (G-SWITCH
LOOP) IS NOT PROPERLY INSTALLED IN THE ELT D-SUB CONNECTOR.
