HORN/CIGAR LIGHTER
HORN
The horn system uses two switches and horn relay.
The horn switches are on the steering wheel.
Circuit A7 from fuse 3 in the Power Distribution
Center (PDC) feeds a fuse block bus bar that powers
circuit X4 through fuse 11. Circuit X4 is HOT at all
times and powers the coil and contact sides of the
horn relay.
When the case grounded horn switch is depressed,
circuit X3 provides ground for the coil side of the re-
lay and the contacts close. When the contacts close,
circuit X2 supplies voltage to the case grounded
horns.
HELPFUL INFORMATION
²The horn switches are grounded to the steering
wheel.
²Circuit X4 is double crimped at the coil side of the
horn relay.
²Check fuse 3 in the PDC and fuse 11 in the fuse
block.
CIGAR LIGHTER
In the ACCESSORY or RUN position, the ignition
switch supplies voltage to fuse 2 in the fuse block on
circuit A48. Fuse 2 feeds circuit F85 which connects
to the cigar lighter. When the lighter is depressed,
the contacts inside of the lighter element close and
voltage flows to ground on circuit Z1.
HELPFUL INFORMATION
²In the ACCESSORY or RUN position, the ignition
switch connects circuit A1 from fuse 6 in the PDC
with circuit A48.
²Circuit F85 also powers the radio and LCD relay.

left courtesy lamp, right courtesy lamp, dome lamp,
and cargo lamp. The M1 circuit also connects to the
remote keyless entry module. Circuit M1 is protected
by the ignition off draw (IOD) fuse (fuse 9) in the fuse
block.
Circuit E2 supplies power for the instrument panel
illumination lamps.
INSTRUMENT PANEL ILLUMINATION LAMPS
Circuit E2 from the headlamp switch splices to
supply power to the following illumination lamps:
²Ash receiver lamp
²Cigar lighter lamp
²Transmission range indicator lamp
²Transfer case range indicator lamp
²A/C-Heater switch lamp
²Heated rear window lamp
²Rear wiper switch lamp
²Fog lamp switch lamp
Fuse 19 in the fuse block protects circuit E2. Circuit
Z1 provides ground for all of the illumination lamps
except for the cigar lighter lamp. The cigar lighter
lamp is case grounded.
HELPFUL INFORMATION
Circuit E2 also supplies power to the radio, LCD
relay and the illumination lamps in the instrument
cluster.
IGNITION SWITCH LAMP
The time delay relay is used to allow a time-ON
function for the ignition switch lamp and the courtesy
lamp. Power for the relay is received on the M1
circuit from the IOD fuse (fuse F9) in the fuse block.
Circuit M2 provides ground for the time delay relay
through the right and left door ajar switches and the
headlamp switch. When a door is opened, or the
headlamp switch is moved to the dome lamp position,a ground path is provided for the relay on circuit M2.
This energizes the relay, causing the contacts to close.
When the relay contacts close, power is provided
through the relay to circuit M50. The M50 circuit
supplies current to the ignition switch lamp. Circuit
Z1 provides ground for the lamp.
GLOVE BOX LAMP
Circuit M1 from the IOD fuse (fuse F9) in the fuse
block powers the glove box lamp. A case grounded
switch, in series after the lamp, closes when the glove
box door is opened. The switch completes a path to
ground on circuit Z1.
CARGO LAMP, COURTESY LAMPS AND DOME
LAMP
Circuit M1 from the IOD fuse (fuse F9) in the fuse
block supplies power to the cargo, courtesy lamps and
dome lamp. This circuit is HOT at all times. The
ground path for the lamp is provided in three differ-
ent ways.
One way is through the door jamb switches. Circuit
M2 connects to the door jamb switches from the cour-
tesy and dome lamps. The switches are connected to
ground circuit Z1. When a door is opened, the plunger
in the switch closes, completing a path to ground.
The second way is through the liftgate switch. Cir-
cuit M2 connects to circuit M4 at the cargo lamp.
Circuit M4 connects to the liftgate switch. The lift-
gate switch connects to ground circuit Z1. When the
lift gate opens, the plunger in the switch closes, com-
pleting a path to ground.
The third ground path is through the headlamp
switch. Circuit M2 is spliced in with the headlamp
switch. When the operator turns the headlamp switch
to the dome lamp ON position, a ground path is
provided through the switch.
J8W-44 INTERIOR LIGHTINGÐXJ VEHICLES 8W - 44 - 1

AUDIO SYSTEM
RADIO
When the ignition switch is in the ACCESSORY or
RUN position, it connects circuit A1 from fuse 6 in the
Power Distribution Center (PDC) to circuit A48. Cir-
cuit A48 powers circuit F85 through fuse 2 in the fuse
block. Circuit F85 powers the radio.
Circuit Z1 provides ground for the radio. The an-
tenna connects to the rear of the radio.
RADIO MEMORY
Circuit M1 from the Ignition Off Draw (IOD) fuse
(fuse 9) in the fuse block supplies power for the radio
memory. The IOD fuse is removed during vehicle
shipping to prevent excessive battery draw.
Circuit A6 from fuse 16 in the Power Distribution
Center (PDC) supplies voltage to fuse 9. Circuit A7
from fuse 3 in the PDC powers circuit A6 through
fuse 16. Circuits A6, A7 and M1 are HOT at all times.
RADIO ILLUMINATION
Circuit E2 supplies battery voltage to the radio
illumination lamps when the headlamps or parking
lamps are on and the dimmer switch is in the LOW or
ON positions.
Circuit X5 supplies battery voltage for the radio
clock and station frequency display. Circuit X5 origi-
nates at the radio illumination relay and is fed by
either circuit F85 or circuit E2 depending on the
switch position inside the relay.
When the headlamps and parking lamps are off, the
radio illumination relay is in its normal At Rest posi-
tion. In the At Rest position, the relay connects circuit
F85 from fuse 2 in the fuse block to circuit X5.
When the headlamps or parking lamps are on, cir-
cuit L90 from the headlamp switch supplies battery
voltage to the coil side of the radio illumination relay.
Circuit Z1 provides ground for the coil side of the
relay.
When voltage is present on circuit L90, the radio
illumination relay switches from its At Rest position
to connect circuit E2 to circuit X5.

connector. Circuit G71 connects to the liftgate switch.
The liftgate switch connects to ground circuit Z1.
When the lift gate opens, the plunger in the switch
closes, completing a path to ground.
The third ground path is through the headlamp
switch. Circuit M2 is spliced in with the headlamp
switch. When the operator turns the headlamp
switch to the dome lamp ON position, a ground path
is provided through the switch.
READING LAMPS
Circuit M1 from fuse 16 in the Power Distribution
Center (PDC) supplies power to the reading lamps.
Circuit M1 is HOT at all times. When the operator
depresses the reading lamp, the reading lamp switch
closes and supplies ground on circuit Z1.
VISOR VANITY MIRROR LAMPS
Circuit M1 from fuse 16 in the Power Distribution
Center (PDC) supplies power to the vanity lamps.
Circuit M1 is HOT at all times. When the vanity
lamps switch closes, voltage flows to vanity mirror
lamps. The vanity mirror is case grounded.
UNDERHOOD LAMP
Circuit A7 from fuse 16 in the Power Distribution
Center (PDC) supplies battery voltage for the under-
hood lamp. A mercury switch, in series after the
lamp, connects the lamp to ground on circuit Z1.
When the hood is raised, mercury inside the switch
moves to a position where it connects circuit M1 to
ground circuit Z1, illuminating the lamp.
