Electrical Connections
Connections to the 802-009 are made through a single 55 pin MIL-C-26500 cylindrical bayonet coupling
type connector. The mating connector to be installed on the aircraft wire harness comes with a coupling
nut. A cable support is recommended for strain relief of wires exiting the mating connector.
