SECONDARY IGNITION WIRINGSecondary ignition wiring is shown in Figs 1 and 2.

For additional information on ignition systems or dis-tributor operation refer to Group 8D Ignition Sys-tems.

WIRING DIAGRAM SHEETS AND INDEXESThe wiring diagram sheets are organized to show

systems relating to the basic vehicle and all of itsoptions. Add-on or non-factory options are not cov-ered. Diagram pages are identified by a sheet numberwhich is located at the lower right or left hand cornerof each sheet. Page numbers at the top of eachpage do not apply to diagram sheets.

Diagram sheets show all information relating to thesystem. This includes feeds, grounds, switch internalcircuity, connectors, splices, and pin identification forcontrollers and modules.

In certain instances a wire may be referenced toanother sheet. When this happens, the wire will be

identified as to what it is ie: feed, ground etc, andwhere it is going (Fig. 3). This has been done to aid inthe diagnosis of wiring and component problems.

The index for the diagrams is located at the begin-ning. It covers all systems shown in the diagrams andis in alphabetical order. The main system and allrelated components are covered.

WIRE CODE IDENTIFICATIONEach wire shown in the diagrams contains a code

(Fig. 4) which identifies the main circuit, part of themain circuit, gauge of wire, and color. The color isshown as a two letter code which can be identified byreferring to the Wire Color Code Chart (Fig. 5). If thewire has a tracer and it is a standard color an aster-isk will follow the main wire color. If the tracer isnon-standard the main wire color will have a slash (/)after it followed by the tracer color.

CIRCUIT IDENTIFICATIONAll circuits in the diagrams use an alpha/numeric

code to identify the wire and its function. To identifywhich circuit code applies to a system, refer to theCircuit Identification Code Chart. This chart showsthe main circuits only and does not show the second-ary codes that may apply to some models.

LOCATING A SYSTEMTo locate a system or component in the diagrams,

refer to the alphabetical index at the front of thediagrams. Determine the diagram sheet number.Sheet numbers are located at the lower right or lefthand corner of each sheet. Page numbers at thetop of the page do not apply to diagram sheets.

The index identifies the main system and all compo-nents that relate to that system. There are also sec-tions of the index that identify specific componentsonly (for example modules, lamps, etc.). Refer to acomponents name in the index if you are unclear as towhat a system may be called.

Diagram sheets are arranged starting with the bat-tery and fuses. Then working into charging, starting,and ignition systems. After this they start at the frontof the vehicle and work to rear of the vehicle. Thediagrams end with connector identification pages.

COMPONENT IDENTIFICATIONWhen looking for a components location on the ve-

hicle refer to the wiring and components section.

This section shows the wire harness routing and thecomponents location in the vehicle. To use this sectionrefer to the wiring diagrams for the general locationof 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 it (Fig. 6example 1). If there is more than one splice per circuita small box will be connected to it with the splicenumber in it (Fig. 6 example 2).

To locate a splice in the wiring harness determinethe splice number from the diagrams then refer to thesplice location index. This section shows the generallocation of the splice in the harness.

CONNECTORSThe connectors shown in the diagram sheets are

viewed from the terminal end unless otherwise speci-fied. For viewing bulkhead, powertrain control mod-ule, and transmission control module connectors refer

to the rear of the wiring diagrams. This area showsmajor connectors and identifies pin and cavity infor-mation.

TROUBLESHOOTING WIRING PROBLEMSWhen troubleshooting wiring problems there are six

steps which can aid in the procedure. The steps arelisted and explained below.

(1) Verify the problem.(2) Verify any related symptoms. Do this by per-

forming operational checks on components that are inthe same circuit. Refer to the wiring diagrams fuseapplication chart.

(3) Analyze the symptoms. Use the wiring dia-grams to determine what the circuit is doing, wherethe problem most likely is occurring and where thediagnosis will continue.

(4) Isolate the problem area.(5) Repair the problem.(6) Verify proper operation. For this step check for

proper operation of all items on the circuit repaired.Refer to the wiring diagram fuse application chart.

HARNESS REPAIR

WIRING REPAIRWhen replacing or repairing a wire, it is important

that the correct gauge be used as shown in the wiringdiagrams. The wires must also be held securely inplace to prevent damage to the insulation.

(1) Disconnect battery negative 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 enoughto cover and seal the entire repair area.

(4) Spread the strands of the wire apart on eachpart of the exposed wires (Fig. 7 example 1).

(5) Push the two ends of wire together until thestrands of wire are close to the insulation (Fig. 7example 2).

(6) Twist the wires together (Fig. 7 example 3).(7) Solder the connection together using rosin core

type solder only. Do not use acid core solder.(8) Center the heat shrink tubing over the joint and

heat using a heat gun. Heat the joint until the tubingis tightly sealed and sealant comes out of both ends ofthe tubing.

(9) Secure the wire to the existing ones to preventchafing or damage to the insulation.

(10) Connect battery and test all affected systems.

CONNECTOR REPLACEMENT(1) Disconnect battery.(2) Disconnect the connector that is to be repaired

from its mating half.(3) Remove connector locking wedge (Fig. 8).(4) Position the connector locking finger away from

the terminal. Pull on the wire to remove the terminalfrom the connector (Fig. 9).

(5) Reset the terminal locking tang, if it has 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 intothe proper cavities. For additional connector pin outidentification 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) Disconnect Battery.(2) Disconnect the connector being repaired from

its mating half.(3) Cut off the existing wire connector directly be-

hind the insulator. Remove six inches of tape from theharness.

(4) Stagger cut all wires on the harness side about1/2 inch apart (Fig. 10).

(5) Remove 1 inch of insulation from each wire onthe harness side.

(6) Stagger cut the matching wires on the repairconnector assembly in the opposite order as was doneon the harness side of the repair. Allow extra lengthfor soldered connections. Check that the overalllength is the same as the original (Fig. 10).

(7) Remove 1 inch of insulation from each wire.
