C. ELT 22-Pin Plug Installation
(1) Refer to "Figure 21. Remote Switch Harness Wiring Diagram”, on page 69, and "Figure 22.
Harness ELT 22-Pin Plug Arrangement".
Figure 22. Harness ELT 22-Pin Plug Arrangement
(2) Fabricate two short jumper wires, approximately 1.5 in. (38 mm) long.
(a) Strip approximately 0.19 in. (5 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) Crimp contact sockets (151-6657) on the wire ends.
NOTE: Use crimp tool M22520/7-01 and die M22570/7-06, or equivalent.
(3) Terminate the jumpers in the harness ELT 22-position plug (150-5061) as follows:
CAUTION: THE ELT WILL NOT AUTOMATICALLY ACTIVATE IF THE G-SWITCH LOOP
JUMPER (PINS 12 AND 13) IS NOT PROPERLY INSTALLED IN THE HARNESS ELT
PLUG.
(a) Insert the contact sockets of one jumper in Pins 12 and 13 (G-switch loop).
NOTE: Use insertion tool MS27495A22MS, or equivalent, and extraction tool
MS27495R22MS, or equivalent.
NOTE: Each contact socket should “click” into place when properly seated.
(b) Insert the contact sockets of the other jumper in Pins 3 and 4.
(4) Slip the strain relief (151-5061) over the wiring terminating in the harness ELT plug.
NOTE: Slide heat shrink tubing of suitable size over the wires, if desired.
(5) Insert the harness and other wiring contact sockets in the harness ELT plug as follows:
(a) Harness wires connecting to the remote switch plug.
1 Make a record of wire identification and pin relationships for reference when
terminating the harness wires in the remote switch plug.
(b) The airframe ground wire (Pin 11).
