TM 11-5820-890-30-5
16-2. ELECTRICAL CONNECTOR ASSEMBLY (9A1).
The electrical connector assembly has five connectors as shown in figure 16-1. The operating voltage (22 to 32 V
dc) from the vehicle’s electrical system is connected to the power-in connector (J1). A second mounting base
or other equipment is connected to the power-out connector (J2). The vehicle intercom or LS-671/VRC loud-
speaker is connected to connector J3 or J4. The system connector (J5) mates with the system connector (P1)
on the power supply adapter. See chapter 14.
The electrical connector assembly has no active circuitry. The dc input power is filtered by either filters FL1 and
FL2, or for newer versions the FILTER EMI-CCA. All connections are as shown in figure 16-2.
