3.3 Dash-Mount Accessory Installations for W4/5/7/9 Models
NOTE: This configuration is not applicable for 100W radios.
For dash-mounted configurations, the accessories must be installed through the accessory
connector assembly that is located on the rear of the radio, adjacent to the power connector.
Motorola-approved accessories are supplied with male terminals crimped to a 20-gauge wire
specifically designed to fit the plug of the accessory connector assembly.
Insert the male terminal into the accessory connector assembly in the appropriate location and
connect the accessory connector assembly in the rear accessory port (see
Figure 3-9). Do not use
other generic terminals in the plug. Generic terminals can cause electrical intermittencies and may
cause damage to the plug.
