the diagnosis of wiring and component problems.
The index for the diagrams is located at the begin-

WIRE CODE IDENTIFICATIONE a c h w i r e s h o wn i n t h e d ia g r a m s con t a i n s a cod e
(Fig. 4) which identifies the main circuit , part of the
main circuit , gauge of wire, and color. The color is
shown as a two letter code which can be identified by
referring to the Wire Color Code Chart (Fig. 5). If the
w i r e h a s a t r a c e r a n d i t i s a s t a n d a r d c o l o r a n a s t e r -
isk will follow the main wire color. If t he tra cer is
non-standard the main wire color will have a slash (/)
after it followed by the tracer color.
CIRCUIT IDENTIFICATIONAl l ci r cu i t s i n t h e d ia g r a m s u s e a n a l ph a /n u m e r i c
code to identify the wire and its function. To identify
which circuit code applies to a system, refer to th eCircuit Identification Code Chart. This chart shows
the main circuits only and does not show the second-
ary codes that may apply to some models.

This section shows the wire harness routing and the
components location in the vehicle. To use this section
refer to the wiring diagrams for the general location
of the component. Then use the component identifica-
tion index to locate the proper figure number.
SPLICE LOCATIONSSplice locations are indicated in the diagrams by a
diamond with a splice circuit code within i t (Fig. 6
example 1). If there is more th an one splice per circuit
a s m a ll b ox w il l b e con n e ct e d t o i t w it h t h e s p li ce
number in it (Fig. 6 example 2).To locate a splice in the wiring harness determine
the splice num ber from the diagrams then refer to th e
splice locat ion index. This section shows th e genera l
location of the splice in the harness.

TROUBLESHOOTING WIRING PROBLEMSWhen troubleshooting wiring problems there are six
s t e p s w h i c h c a n a i d i n t h e p r o c e d u r e . T h e s t e p s a r e
listed a nd explained below.
(1) Verify the pr oblem.

grams to determine what the circuit is doing, where
the problem most l ikely is occurr ing and where t he
diagnosis will continue.
(4) Isolate th e problem area.
(5) Repair the problem.
(6) Verify pr oper operat ion. For th is st ep check for
proper operation of all i tems on the circuit repaired.
Refer to the wiring diagram fuse application chart.
HARNESS REPAIRWIRING REPAIR
When replacing or repairing a wire, i t is important
tha t t he correct gauge be used as shown in t he wiring
d ia g r a m s . T h e w ir e s m u s t a l so b e h e ld s e cu r e ly i n
place to prevent damage t o the insulation.
(1) Disconnect batt ery negat ive cable.
(2) Remove 1 inch of insulation from each end the
wire.
(3) Place a piece of heat shrink tubing over one side
of the wire. Make sure the tubing will be long enough
to cover and seal the entire repair area.

type solder only. D o n o t u s e a c i d c o r e s o l d e r.(8) Center the h eat shr ink tubing over the joint and
heat using a heat gun. Heat the joint until the tubing
is tightly sealed and sealant comes out of both ends of
the tubing.
(9) Secure the wire to the existing ones to prevent
chafing or damage to th e insulation.
(10) Connect battery and test all affected systems.
CONNECTOR REPLACEMENT
(1) Disconn ect bat ter y.
(2) Disconnect the connector that is to be repaired
from its mating half.

(4) Position th e connector locking finger a way from
the terminal. Pull on the wire to remove the terminalfrom the connector (Fig. 9).
(5) Reset the terminal locking tan g, if i t ha s one.
(6) Insert the removed wire in the same cavity on
the repair connector.
(7) Repeat steps four thru six for each wire in the
connector, being sure that all wires are inserted into
the proper cavities. For additional connector pin out
identification refer to the wiring diagrams.
(8) Insert the connector locking wedge into the re-
paired connector.
(9) Connect connector to its mating half.
(10) Connect battery and test all affected systems.
CONNECTOR AND TERMINAL ASSEMBLY RE-
PLACEMENT
(1) Disconn ect Batt ery.
(2) Disconnect the connector being repaired from
its ma ting ha lf.
(3) Cut off the existing wire connector directly be-
hind the insulator. Remove six inches of tape from the
h a r n e s s .
(4) Stagger cut all wires on the harness side about
1/2 inch apart (Fig. 10).(5) Remove 1 inch of insulation from each wire on
the harness side.
(6 ) S t a g ge r cu t t h e m a t ch i n g w i r es on t h e r e p a ir
connector assembly in the opposite order as was done
on the harness side of the repair. Allow extra length
for s ol de r ed con n e ct i on s . C h e ck t h a t t h e ov er a l l
length is the same as the original (Fig. 10).
(7) Remove 1 inch of insulation from each wire.
