DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE MANUAL
B406-4 (453-5004)
(2) Fabricate a 4-wire harness long enough to reach from the ELT to the cockpit remote switch
panel, allowing enough slack to provide a drip loop at the ELT end and a service loop at the
cockpit remote switch panel end.
NOTE: A 5 or 6-wire harness may be necessary if a ground wire is connected between ELT
Pin 11 and remote switch panel Pin 9; and/or ELT Pin 2 must be connected to remote
switch panel Pin 8 if a horn is not installed. See Figure 19. Remote Switch Panel
Harness Wiring Diagram on page 66.
(a) Strip approximately 0.15 in. (3 mm) of insulation from the ends of each of the harness
wires.
(b) Dress and tin the bare wires to prevent the strands from fraying during terminal
crimping operations.
(3) Fabricate the additional wires needed to connect the remote switch panel; referring to Figure
19. Remote Switch Panel Harness Wiring Diagram on page 66, and the aircraft wiring
diagrams to determine appropriate connection points.
(a) Pin 3 to the selected +28V aircraft power source.
(b) Pin 4 to the selected +28V/+16V aircraft power source.
(c) Pin 6 to the Master Caution +17V circuit.
(d) Pin 8 to the BLUE wire on the buzzer (i.e., horn).
(e) Pin 9 to aircraft ground.
(f) Pin 10 to the Master Caution Pulse circuit.
(g) Pin 11 to the Master Caution Steady State circuit.
(h) Pin 12 to the Master Lighting Test circuit.
(i) Pin 13 to the 5VAC Lighting circuit.
(j) Pin 14 to aircraft ground.
(k) Prepare the wires as described in Steps (2)(a) and (2)(b).
(4) Terminate the remote switch panel end of all wires in an MS24266R16B24S7 connector in
accordance with the aircraft manufacturer’s written instructions or AC43.13-1, as applicable.
See Figure 19. Remote Switch Panel Harness Wiring Diagram on page 66.
NOTE: Identify the wires and connector pin relationships, such that the wiring can be
terminated at the appropriate locations.
(5) Install the remote switch panel harness as follows:
(a) 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.
(b) Route the wire bundle through the airframe.
(c) Support the wire bundle by clamping or other suitable means, such that the wiring is
properly supported and protected from chaffing and strain. Refer to the aircraft
