Wiring
WARNING! Only connect the unit to a 12-volt power supply with proper grounding.
Complete wiring as illustrated in the wiring diagram on page 4. Once the wiring is complete,
reconnect the battery negative terminal. If there is no ACC available, connect the ACC lead to the
power supply with a switch.
NOTE: When replacing a fuse, be sure to use correct type and amperage to avoid damaging
the radio. The VM9313 uses one 15 amp fuse, located in the black filter box in-line with the
main wire harness.
Final Installation
After completing the wiring connections, turn the unit on to
confirm operation (ignition switch must be on). If unit does
not operate, recheck all wiring until problem is corrected.
Once proper operation is achieved, turn off the ignition
switch and proceed with final mounting of the chassis.
Connect wiring adapter to existing wiring harness.
