2.2.3 Locking Kit (Optional)
If a locking kit is used (shown in Figure 2-20), position the lock bottom housing on the trunnion
before installing the radio mounting screws. Then slip the top lock housing on and remove the key.
You can install the lock on either side of the radio, and by rotating it 180°, you can also install it on
dash installations.

2.3 Power Cable
Route the red radio power cable from the radio to the vehicle’s battery compartment, using accepted
industry methods and standards. Be sure to grommet the firewall hole to protect the cable. Remove
the 15-amp (P/N 6580283E06) or 20-amp (P/N 6580283E07) fuse from the fuseholder and connect
the red lead of the radio power cable to the positive battery terminal using the hardware provided as
shown in
Figure 2-21 and Figure 2-22. Connect the black lead to a convenient solid chassis ground
point. DO NOT connect the black lead directly to the battery’s negative terminal.

NOTE:
For remote mount configurations, do not supply IGNITION at the radio’s rear accessory connector. IGNITION should be supplied according to Table 2-1.
(See Table 2-1 for combinations of wiring the Green and Orange Cables)
The orange and green power cables connect to either the vehicle battery or the ignition switch. Connect the green cable directly to the battery. The receiver operates
when the control head is on. Connect the orange cable to the ignition switch. The transmitter operates only when the ignition switch is on.
Alternate connections:
Connecting both green and orange cables to the battery allows the control head to turn the receiver and transmitter on or off. Connecting both green and orange cables
to the ignition switch allows the ignition switch to turn the receiver and transmitter on or off. (Alternator whine and other noise problems may occur. Isolate the green
cable with a Motorola relay, part #59-00813674.)
