FIGURE 7 - (MODEL 124 SHOWN)
Remove the spring contact with harness and discard (arrow, Figure 7) and install a harness with positive-lock coupling and spring tab (1 and 2, Figure 6)
whenever a defective radio chassis is replaced (refer to modification procedure).
FIGURE 8
To connect a positive-lock coupling to a radio chassis, the bottom cover of the radio chassis must have a spade connector (arrow, Figure 8) at its rear
center (when installed). If not so equipped, the bottom cover must be replaced.
FIGURE 9
Note:
When removing a radio chassis equipped with the positive-lock plug connection, the spring tab (2, Figure 9) is pushed against the console
causing the positive-lock coupling to slide off the spade connector.
