Connecting to Power Without Using an Ignition Switch
This method of connection is used most often on larger vehicles and on vehicles with multiple networked
stereos and other devices. For these installations, a faster startup time is typically less critical, and it is more
effective to use the breaker or a dedicated switch on the electrical panel to turn off the stereo and ensure that
no unexpected power drain occurs.

Notes
You should connect this wire to the red wire before you connect both wires
to the manual switch or circuit breaker.
You should connect this wire to the yellow wire so that it does not act as a
physical standby switch.
You must install this fuse on the red wire before you connect the red wire
to the yellow wire.
This switch is needed only if a circuit breaker is not available or if it
provides a more convenient method of cutting power to the stereo.
Ground (-)
