6. 453-0032 WIRING TO 453-0041
6.1 INSTRUCTIONS
6.1.1 The size of the two wires is based on the D-sub crimp contact 151-0042 accepting 22 to 26
gauge wires.
6.1.2 The color of the two communication wires between the interfaces is inconsequential, but each
wire must be properly connected to the appropriate contact on the D-sub mating connector.
6.1.3 The following information highlights the wiring between the two interfaces:
Table 5: Communication Wires
6.1.4 The ends of the two communication wires are crimped and inserted inside the D-sub connector
150-0022 using the same procedure highlighted in the
“Crimping Instructions” section 4.
NOTE: Do not close the backshell if additional wiring to the D-subs is necessary. Refer to the
appropriate sections in this document to complete the entire wiring process.
6.1.5 Install the D-sub connector inside a backshell (151-0006) at the completion of the crimping
process.
6.1.6 Install each D-sub connector inside a backshell (151-0006).
6.1.7 Secure the strain relief using the screws provided in the backshell kit.
6.1.8 Install the thumbscrews and close the backshell with the screws.
6.1.9 Attach each backshell to the appropriate interface using a torque between 1.5 and 2.0 in-lb (.7 to
.22 Nm) at the completion of the entire wiring process.
NOTE: Accidently attaching the wrong interface to a backshell does not harm the ELT, the toggle
switch 140-3349, or any of the interfaces. The outcome is that the ELT cannot be
activated remotely through the toggle switch 140-3349.
