GENERAL INFORMATION
Following are general descriptions of major compo-
nents used in XJ (Cherokee)/YJ (Wrangler) audio sys-
tems. Refer to Group 8W - Wiring Diagrams for
complete circuit descriptions and diagrams.
RADIOS
Radio options for the XJ and YJ models include an
AM/FM stereo or an AM/FM stereo/cassette receiver.
Both units are Electronically-Tuned Radios (ETR)
and include a clock function. For more information
on radio features, setting procedures, and control
functions refer to the owner's manual.
IN-LINE FUSE
Each radio receives fused battery feed when the ig-
nition switch is in the ON or ACCESSORY position.
There is an additional in-line fuse in the back of the
radio chassis. The in-line fuse (Fig. 1) will blow to
protect the vehicle electrical system in the event of
internal radio failure.
IGNITION-OFF DRAW FUSE
All vehicles are equipped with an Ignition-Off
Draw (IOD) fuse that is removed when the vehicle is
shipped from the factory. This fuse feeds various ac-
cessories that require current when the ignition
switch is in the OFF position, including the clock and
radio station preset memory functions. The fuse is re-
moved to prevent battery discharge during vehicle
storage.The IOD fuse should be checked if the radio station
preset memory or clock functions are erratic or inop-
erative. The IOD fuse is located in the Power Distri-
bution Center (PDC). Refer to underside of PDC
cover for IOD fuse identification.
RADIO ILLUMINATION RELAY
All radios are connected to a radio illumination re-
lay. The relay controls the source of battery feed for
radio/clock display illumination.
When the park and headlamp switch is in the OFF
position, the radio illumination relay remains de-en-
ergized. The radio/clock display receives full battery
voltage through the normally closed contacts of the
relay. This results in the radio/clock display being il-
luminated at full brightness for easier visibility in
daylight.
When the park and headlamp switch is in the ON
position, the radio illumination relay coil is ener-
gized. With the relay coil energized, the normally
closed contacts of the relay open, and the normally
open contacts of the relay close. This causes the ra-
dio/clock display to receive battery feed through the
instrument panel dimmer switch. The display illumi-
nation brightness can now be adjusted with other
panel lamps for night visibility.
SPEAKERS
Speaker system options include two, four or six (XJ
only) speaker locations. On XJ model two-speaker
systems, one speaker is located in each front door.
Four-speaker systems add one speaker at each end of
a rear-mounted overhead sound bar. The premium
six-speaker option upgrades all the speakers in the
above locations, and adds one tweeter at each end of
the lower instrument panel.
On YJ model two-speaker systems, one speaker is
located at each end of the instrument panel. Four-
speaker systems add one speaker at each end of a
rear-mounted overhead sound bar.
