3. Obtain the black-wired blade fuse holder included with the radio’s DC Power Cable, and crimp one
half of it to one end of the short section of wire.
4. Using an appropriate electrical terminal, connect this short white wire to unswitched 12-volt DC power
source at or near the vehicle’s fuse box.
5. Cut another section of white wire from the cable. This wire must be long enough to reach from the fuse
holder to the location of the panel-mounted on/off switch.
6. Strip one end of this wire and crimp the other half of the waterproof fuse holder to this wire end.
7. Strip the other end of this wire and, using an appropriate electrical terminal, connect it to the common
terminal of the switch.
8. Connect the white wire of the power cable to the load (switched) side of the switch.
9. If not already, mount the switch to the vehicle’s dash panel, or other customer-selected location.
10. Obtain the 3-amp blade fuse included with the cable and install it into the fuse holder.
11. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe
is avoided.
12. Label this power switch accordingly. For example: “RADIO ON/OFF.”
13. Continue with the speaker installation procedures presented in Section 10.1 on page 78.
8.2.3.3 Radio Is “Hot Wired”
In the “hot-wired” configuration, the radio (and its Control Head) is turned on and off only by the Control
Head’s on/off/volume control located on the front panel of the Control Head. In this configuration, the
white wire must be connected to unswitched and fused 12-volt vehicle power.
Follow the procedure presented in Section 8.2.3.1, except connect the white wire to unswitched battery
power instead of switched (“Accessory”) power. Be sure to fuse this connection with the provided in-line
fuse holder and 3-amp blade fuse.
