Accessory Connector Assembly Details (P2)
The APX mobile accessory connector assembly is mounted on the right rear of the radio, opposite the
antenna and next to the power connector.
It is fastened to the radio via jackscrews and held together by the two cover screws. It is a multi-
functional connector that allows for many different types of adaptations. All approved accessory wires
are securely strain-relieved through the exiting slots at the back of the accessory connector assembly.
The terminations that are supplied with all accessories are fully engaged and locked into the plug
connector (6680163F01). They can also be detached for service with the assistance of a terminal
removal tool. The accessory connector assembly can be serviced multiple times for future installation
upgrades.
The accessory connector assembly, supplied with every APX mobile dash-mounted radio, is equipped
with a 26-pin plug assembly, two covers, two jackscrews, two cover screws, one emergency jumper,
one ignition sense cable assembly, and one speaker pigtail. The jumper is provided to complete the
circuit for emergency mode. If this circuit becomes open, the radio is set to emergency mode.
3980034F05 is the crimping pin part number for use with any wires used inside the accessory cable
connector.
