After selection of the AID, the proper pins on the KRA 405 R/T connector must be jum-
pered.

drawing.
During preparation of the wiring harness, observe the following precautions:
2.4.5.A
Bond and shield all parts of the aircraft electrical system such as generators
and ignition systems.
2.4.5.B
Keep the cables away from circuits carrying heavy current, pulse-transmitting
equipment, 400 Hz circuits, and other sources of interference.
2.4.5.C
Make all external connections of the equipment through designated connec-
tors listed on the diagram.
2.4.5.D
Wire size is specified on the interconnect diagram.
2.4.5.E
Leave slack in cables to allow for free sway of the equipment.
2.4.5.F
After installation of the cables in the aircraft and before installation of the
equipment, a check should be made to ensure that the aircraft power is ap-
plied only to the pins specified.
