GENERAL INFORMATION
Circuit M1 supplies power to the glove box lamp,
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.

READING LAMPS
Circuit M1 from the IOD fuse (fuse F9) in the fuse
block 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 the IOD fuse (fuse F9) in the fuse
block 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 van-
ity mirror is case grounded.
UNDERHOOD LAMP
Circuit A6 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.
CHIME/BUZZER MODULE
The buzzer or optional chime module sounds an au-
dible warning tone. The tone sounds for seat belt
warning and when the ignition key is in the ignition
switch while the drivers door is open. The tone also
sounds when the ignition key is in the ON position
while the drivers side seat belt is not buckled. Lastly,
the tone sounds when the headlamps are ON when
the ignition is OFF. Refer to Group 8U for system op-
eration.
When the ignition switch is in the RUN or START
position, circuit F87 from fuse 17 in the fuse block
supplies power to the chime/buzzer module. Circuit
A21 from the ignition switch supplies power to fuse
17.
Circuit L7 from fuse 15 in the fuse block also sup-
plies power to the chime/buzzer module. Circuit A3
from fuse 5 in the Power Distribution Center (PDC)
powers fuse 15.
When the parking lamps or headlamps are ON, the
headlamp switch connects circuit G26 with the driv-
ers side door jamb switch. Circuit G26 also connects
to the key-in switch. Circuit M11 connects the key-in
switch to the chime/buzzer module and the headlamp
switch.
If the headlamps are ON, and the drivers door
opens, ground for the chime/buzzer is on circuit C26
from the headlamp switch through the door jamb
switch to circuit Z1.
If the headlamps are OFF with the key in the ig-
nition while the drivers side door is open, ground forthe chime/buzzer is supplied through the key-in
switch. The ground path is over circuit M11, through
the closed key-in switch to circuit C26. From circuit
C26, the ground path continues through the drivers
door jamb switch to circuit Z1.
Circuit G11 from the buzzer powers the seat belt
warning lamp in the instrument cluster. Circuit Z1
at the instrument cluster provides ground for the
lamp.
Circuit G10 from the buzzer connects to the seat
belt switch. When the seat belt switch closes a path
to ground is completed on circuit Z1 and the tone
sounds momentarily.
Circuit Z1 also grounds the chime\buzzer module.
HELPFUL INFORMATION
Circuit F87 also powers the instrument cluster and
the headlamp delay module.

GENERAL INFORMATION
Circuit M1 supplies power to the underhood lamp,
dome lamp, right courtesy lamp and left courtesy
lamp. Fuse 12 in the Power Distribution Center
(PDC) protects circuit M1. Circuit A4 from fuse 8 in
the PDC supplies voltage to fuse 12 and circuit M1.
Fuse 12 is referred to as the Ignition Off Draw (IOD)
fuse.
COURTESY LAMPS AND DOME LAMPS
Circuit M1 supplies battery voltage to the dome
lamps and the right and left courtesy lamps. Circuit
M2 provides ground for the lamps through either the
case grounded door jamb switches or through the
dimmer switch to circuit Z1.
In the ON position, the dimmer switch connects
circuit M2 to ground on circuit Z1. When a door
opens, the case grounded door jamb switch closes and
provides ground for the lamps on circuit M2.
HELPFUL INFORMATION
²Circuit M1 also supplies voltage for radio memory,
underhood lamp and the ABS data link connector.
UNDERHOOD LAMP
Circuit M1 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 circuit Z1, il-
luminating the lamp. The underhood lamp is wired
in parallel with other components on circuit M1.
ACCESSORY LAMP AND HEATER CONTROL PANEL
LAMP
Circuit E1 from the dimmer switch supplies bat-
tery voltage to fuse 10 in the fuse block when the
dimmer switch is in the LOW or ON position. Fuse
10 protects circuit E2 which supplies power to the
heater control panel lamp and the accessory lamp.
Circuit Z1 provides ground for each lamp.
TRANSMISSION RANGE LAMP
Circuit E1 from the dimmer switch supplies bat-
tery voltage to fuse 10 in the fuse block when thedimmer switch is in the LOW or ON positions. Fuse
10 protects circuit E2 which supplies power to the
transmission range lamp. The lamp is case grounded.
COMBINATION BUZZER
The combination buzzer module sounds an audible
warning tone. The tone sounds for seat belt warning
and when the key is in the ignition switch while the
drivers door is open. The tone also sounds when the
ignition switch is in the ON position while the driv-
ers side seat belt is not buckled. Refer to Group 8U
for buzzer operation.
Fuses 3 and 9 in the fuse block protect the combi-
nation buzzer. Fuse 3 powers circuit F32 which con-
nects to the buzzer. Circuit A6 from fuse 3 in the
Power Distribution Center (PDC) supplies power to
the fuse block for circuit F32.
Circuit G5 from fuse 9 also provides voltage to the
combination buzzer when the ignition switch is in
the START or RUN position. The ignition switch con-
nects circuit A1 from fuse 4 in the PDC to circuit
A21. Circuit A21 connects to the fuse block.
When the key-in switch closes, it connects circuit
G26 to circuit G16. Circuit G16 connects to the driv-
ers side door jamb switch. When the drivers side door
is open and the key-in switch is closed, the case
grounded door jamb switch closes and supplies
ground for the buzzer. Circuit G26 from the combina-
tion buzzer connects to the key-in switch.
Circuit G13 form the buzzer powers the seat belt
warning lamp in the instrument cluster. Circuit Z1
at the instrument cluster provides ground for the
lamp.
Circuit G10 from the buzzer connects to the seat
belt switch. When the seat belt is unlatched, the seat
belt switch closes providing ground on circuit Z1.
Circuit Z1 also grounds the combination buzzer
module.
HELPFUL INFORMATION
²Circuit F32 also powers the stop lamp switch.
²Circuit G5 also provides power for the instrument
cluster gauges and warning lamps, heated rear win-
dow relay and A/C compressor clutch relay. On Cana-

minutes). The use of a locating dowel is recom-
mended during assembly to prevent smearing the
material off location.
Mopar Gasket Maker should be applied sparingly
to one gasket surface. The sealant diameter should
be 1.00 mm (0.04 inch) or less. Be certain the mate-
rial surrounds each mounting hole. Excess material
can easily be wiped off. Components should be
torqued in place within 15 minutes. The use of a lo-
cating dowel is recommended during assembly to pre-
vent smearing the material off location.
ENGINE PERFORMANCE
To provide best vehicle performance and lowest ve-
hicle emissions, it is most important that the tune-up
be done accurately. Use the specifications listed on
the Vehicle Emission Control Information label found
on the engine compartment hood.
(1) Test battery specific gravity. Add water, if nec-
essary. Clean and tighten battery connections.
(2) Test cranking amperage draw (refer to Group
8B, Battery/Starter Service for the proper proce-
dures).
(3) Tighten the intake manifold bolts (refer to
Group 11, Exhaust System and Intake Manifold for
the proper specifications).
(4) Perform cylinder compression test:
(a) Check engine oil level and add oil, if neces-
sary.
(b) Drive the vehicle until engine reaches normal
operating temperature.
(c) Select a route free from traffic and other
forms of congestion, observe all traffic laws and
briskly accelerate through the gears several times.
The higher engine speed may help clean out valve
seat deposits which can prevent accurate compres-
sion readings.
CAUTION: DO NOT overspeed the engine.
(d) Remove all spark plugs from engine. As spark
plugs are being removed, check electrodes for ab-
normal firing indicatorsÐfouled, hot, oily, etc.
Record cylinder number of spark plug for future
reference.
(e) Disconnect coil wire from distributor and se-
cure to good ground to prevent a spark from start-
ing a fire.
(f) Be sure throttle blades are fully open during
the compression check.
(g) Insert compression gage adaptor into the
No.1 spark plug hole. Crank engine until maximum
pressure is reached on gauge. Record this pressure
as No.1 cylinder pressure.
(h) Repeat Step 4g for all remaining cylinders.
(i) Compression should not be less than 689 kPa
(100 psi) and not vary more than 172 kPa (25 psi)
from cylinder to cylinder.(j) If cylinder(s) have abnormally low compres-
sion pressures, repeat steps 4a through 4h.
(k) If the same cylinder(s) repeat an abnormally
low reading, it could indicate the existence of a
problem in the cylinder.
The recommended compression pressures are
to be used only as a guide to diagnosing engine
problems. An engine should NOT be disassem-
bled to determine the cause of low compression
unless some malfunction is present.
(5) Clean or replace spark plugs as necessary. Ad-
just gap (refer to Group 8D, Ignition System for gap
adjustment and torque).
(6) Test resistance of spark plug cables (refer to
Group 8D, Ignition System).
(7) Inspect the primary wire. Test coil output volt-
age, primary and secondary resistance. Replace parts
as necessary (refer to Group 8D, Ignition System and
make necessary adjustment).
(8) Perform a combustion analysis.
(9) Test fuel pump for pressure (refer to Group 14,
Fuel System for the proper specifications).
(10) Inspect air filter element (refer to Group 0,
Lubrication and Maintenance for the proper proce-
dure).
(11) Inspect crankcase ventilation system (refer to
Group 0, Lubrication and Maintenance for the proper
procedure).
(12) For emission controls refer to Group 25, Emis-
sion Controls System for service procedures.
(13) Inspect and adjust accessory belt drives (refer
to Group 7, Cooling System for the proper adjust-
ments).
(14) Road test vehicle as a final test.
HONING CYLINDER BORES
Before honing, stuff plenty of clean shop towels un-
der the bores and over the crankshaft to keep abra-
sive materials from entering the crankshaft area.
(1) Used carefully, the Cylinder Bore Sizing Hone
C-823 equipped with 220 grit stones, is the best tool
for this job. In addition to deglazing, it will reduce
taper and out-of-round as well as removing light
scuffing, scoring or scratches. Usually a few strokes
will clean up a bore and maintain the required lim-
its.
CAUTION: DO NOT use rigid type hones to remove
cylinder wall glaze.
(2) Deglazing of the cylinder walls may be done if
the cylinder bore is straight and round. Use a cylin-
der surfacing hone, Honing Tool C-3501, equipped
with 280 grit stones (C-3501-3810). 20-60 strokes, de-
pending on the bore condition, will be sufficient to
provide a satisfactory surface. Using honing oil
C-3501-3880 or a light honing oil available from ma-
jor oil distributors.

(6) Apply bead of Loctite 599 sealer to oil pan seal-
ing surface. Sealer bead should be at least 3 mm (1/8
in.) wide. Then install pan and tighten pan bolts to 7
Nzm (65 in. lbs.) torque.
(7) Install new gasket on oil pan drain plug. Install
and tighten plug to 20 Nzm (15 ft. lbs.) torque.
(8) Connect cable to engine bracket and throttle
linkage.
(9) Fill transmission with Mopar Dexron/Mercon
IIE.
(10) Adjust the cable as described in cable adjust-
ment procedure.
TRANSMISSION THROTTLE CABLE ADJUSTMENT
(1) Shift transmission into Park, shut engine off
and raise hood.
(2) Press cable release button (Fig. 44).
(3) Push cable conduit back into cable sheath as
far as possible (Fig. 45).
(4) Rotate lever on throttle body to wide open
throttle position. Cable will ratchet to correct adjust-
ment point as lever is rotated (Fig. 45).
