B. Remote Switch Harness Fabrication
(1) See Figure 20.
Figure 20 Remote Switch Harness Arrangement
(2) Fabricate a 5-wire harness long enough to reach from the ELT to the cockpit remote switch,
allowing enough slack to provide a drip loop at the ELT end and a service loop at the cockpit
remote switch end. See "Figure 21 Remote Switch Harness Wiring Diagram” on page 66.
NOTE: If an ELT/NAV Interface (453-6500) is being installed with the ELT, refer to the “ELT/
NAV Interface Abbreviated Component Maintenance Manual” (570-4602) for
additional wiring instructions.
(a) Strip approximately 0.15 in. (3 mm) of insulation from the ends of each of the five cable
wires.
(b) Dress and tin the bare wires to prevent the strands from fraying during terminal
crimping operations.
(3) Three additional wires are required. See "Figure 21 Remote Switch Harness Wiring Diagram”
on page 66.
(a) Fabricate a ground wire long enough to reach from Pin 11 of the harness ELT receptacle
to aircraft ground.
NOTE: 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 plug. Alternatively, the wires may
