manufacturer's written instructions or as described in AC 43.13-1, Chapter 11, § 9
through 12, as applicable.
(6)
Terminate the aircraft side of the wires fabricated in Step (3) at the appropriate connection
points in accordance with the aircraft manufacturer's written instructions or AC 43.13-1, as
applicable. See "Figure 18. Remote Switch Panel Harness Wiring Diagram", on page 66, and
aircraft wiring diagrams.
(7)
Refer to SUBTASK 25-62-03-450-003, for wire termination instructions at the ELT end of the
remote switch panel harness.

Buzzer Wiring Fabrication
(1)
Fabricate the following wires, which correspond with the wires on the buzzer:
NOTE:
(a)
YELLOW wire to harness ELT receptacle.
(b)
BLACK wire to aircraft ground.
(c)
RED wire to +28VDC aircraft battery power source.
(d)
BLUE wire to Pin 8 of the remote switch panel connector.
(e)
Strip approximately 0.15 in. (3 mm) of insulation from the ends of each of the harness
wires.
(f)
Dress and tin the bare wires to prevent the strands from fraying during terminal
crimping operations.
(2)
Splice the fabricated wires to the buzzer wires in a manner acceptable to the aircraft
manufacturer, or as described in AC 43.13-1, Paragraph 11-167, as applicable.
(3)
Support the wiring by clamping or other suitable means, such that the wiring is properly
supported and protected from chaffing and strain. Refer to the aircraft manufacturer's written
instructions or as described in AC 43.13-1, Chapter 11, § 9 through 12, as applicable.

D.
ELT 12-Pin Receptacle Wiring Fabrication and Installation
(1)
Fabricate a ground wire long enough to reach from the harness ELT receptacle to aircraft
ground.
NOTE:
(2)
Feed the harness wires on the ELT end through the mounting frame cap assembly (452-
5052). See "Figure 19. Remote Switch Panel Harness Wiring at ELT End".

Use appropriately coded wires, such that the wires can be identified and terminated
at the appropriate locations.
This wire will be crimped in the same pin as the wire running from Pin 11 of the ELT
receptacle to the cockpit remote switch panel, ONLY if a ground wire is connected
between the ELT and the remote switch panel. Alternatively, the wires may be
spliced in a manner acceptable to the aircraft manufacturer, or as described in AC
43.13-1, Paragraph 11-167, as applicable.
