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 bat-
tery 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
VM9214
R uses one 15 amp fuse, located in the black filter box in-line with the main wire harness.
