Important Protect the power cable from engine heat, sharp edges and 
from being pinched or crushed.
2. Run the supplied power cable (or one with a higher current rating) 
between the radio’s mounting position and the vehicle battery (12 V) 
and cut it to length, allowing approximately 8 inches (20 cm) excess 
at the radio end.
3. Cut the negative (black) and the positive (red) wires where the in-line 
fuse holders will be placed (as close to the power source as possible).
Important Do not install the fuses until the installation is ready to be 
checked. For more information, refer to “Checking the 
Installation” on page 22.
4. Insert each end of the negative wire into each of the fuse 
crimp-terminals and crimp them to force the metal contacts onto 
the wires.
5. Push the two crimp-terminals into the clear plastic fuse cover. Close 
the cover while the next steps are completed.
6. Repeat steps 4 and 5 for the positive wire.
7. Connect the negative wire to the battery ground terminal.
8. Connect the positive wire to the battery positive terminal.
Important Do not install the fuses until the installation is ready to be 
checked. For more information, refer to “Checking the 
Installation” on page 22.
