Throughout this group references may be made to a particular vehicle by letter or number designation. A chart showing the breakdown of these designations is included in the Introduction Section at the front of this service manual. DISTRIBUTOR SECONDARY WIRING Distributor secondary wiring is shown in Figures 1, 2, 3, and 4. For additional information on ignition systems or distributor operation refer to Group 8D Ignition Systems, in this manual. WIRING DIAGRAM SHEETS AND INDEXES The wiring diagram sheets are organized in such a manner that systems relating to the basic vehicle and all of its options are shown, add-on or non-factory options are not covered. Diagram pages are identified by a sheet number which is located at the lower right or left hand corner of each sheet, page numbers at the top of each page do not apply to diagram sheets. Diagram sheets show all information relating to the system. This includes feeds, grounds, switch internal circu- ity, connectors, splices, and pin identification for controllers and modules. In certain instances a wire may be referenced to another sheet. When this happens, the wire will be Fig. 1 Distributor Secondary Wiring — 2.5L Engine Fig. 2 Distributor Cap — 3.0L V6 Engine .

identified as to what it is ie: feed, ground, etc, and where its going (Fig. 5). This has been done to aid in the diagnosis of wiring and component problems. The index used for the diagrams is located at the beginning of the diagrams and covers all systems shown in the diagrams. The index is in alphabetical order and identifies the main system and all related components. WIRE CODE IDENTIFICATION Each wire shown in the diagrams contains a code (Fig. 6) 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. 7). If the wire has a tracer and it is a standard color an asterisk will follow the main wire color. If the tracer is non- standard the main wire color will have a slash (/) after it followed by the tracer color. MAIN CIRCUIT IDENTIFICATION To identify which main circuit code applies to a system, refer to the Main Circuit Identification Code Chart. This chart shows the main feed circuits only and does not show the secondary codes that may apply to some vehicles. LOCATING A SYSTEM To locate a system or component in the diagrams, refer to the alphabetical index at the front of the diagrams. Determine the diagram sheet number. Sheet numbers are located at the lower right or left hand corner of each sheet. Page numbers at the top of the page do not apply to diagram sheets.

The diagram index identifies the main system and all components that relate to that system. There are also sections of the index that identify specific components only (for example modules, lamps, etc.). Refer to a components name in the index if you are unclear as to what a system may be called. Diagram pages are arranged starting with the battery and fuses. Then working into charging, starting, and ignition systems. After this they start at the front of the vehicle and work to rear of the vehicle. The diagrams end with connector identification pages. COMPONENT IDENTIFICATION When looking for a components actual location on the vehicle refer to the wiring and components section index. This section shows the wire harness routing and the components location in the vehicle. When using this section refer to the wiring diagrams for the general location of the component. Then use the component identification index to locate the proper figure number. SPLICE LOCATIONS Splice locations are indicated in the diagrams by a diamond with a splice circuit code within it (Fig. 8 example 1). If there is more than one splice per circuit a small box will be connected to it with the splice number in it (Fig. 8 example 2). To locate a splice in the wiring harness determine the splice number from the wiring diagrams then refer to the splice location index. This section shows the general location of the splice in the harness. The wiring diagrams also indicate what harness the splice is located in. To identify the harness an abbre- viated call out is placed next to the main splice (Fig. 5). Fig. 7 Wire Color Code Chart Fig. 8 Wiring Splice Examples . WIRING DIAGRAMS 8W - 3

CONNECTORS The connectors shown in the diagram sheets are viewed from the terminal end unless otherwise speci- fied. For viewing bulkhead, engine controller, and transmission controller connectors refer to the rear of the wiring diagrams. This area shows major connectors and identifies pin and cavity information. TROUBLESHOOTING WIRING PROBLEMS When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and explained below. (1) Verify the problem. (2) Verify any related symptoms. Do this by perform- ing operational checks on components that are in the same circuit as the problem area. Refer to the wiring diagrams fuse application chart for more information. (3) Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis 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. FUSIBLE LINKS Vehicle wiring harnesses are equipped with fusible links to protect against harness damage in the event of a short in the system. Fusible links are color coded to indicate wire gauge and size. Refer to the fusible link chart for color and gauge identification (Fig. 9). HARNESS REPAIR FUSIBLE LINK REPLACEMENT CAUTION: Do not replace blown fusible links with a standard wire. Only use fusible type wire with hypa- lon insulation or damage to the electrical system could occur. Also make sure correct gauge of wiring is used. Refer to the wiring diagrams for proper gauge and color. When a fusible link blows it is important to find out what the problem is. They are placed in the electrical system for protection against shorts to ground which can be caused by a component failure or various wiring failures. Do not just replace the fusible link to correct the problem. When diagnosing a faulty fusible link it is important to check the wire carefully. In some instances the link may be blown and it will not show through the insulation, the wire should be checked over its entire length for internal breaks. (1) Disconnect battery negative cable. (2) Cut out the blown portion of the fusible link. (3) Strip 1 inch of insulation from each end of the existing fusible link. (4) Place a piece of heat shrink tubing over one of side of the fusible link. Make sure the tubing will be long enough to cover and seal the entire repair area. (5) Cut a replacement piece of fusible link approxi- mately two inches longer than the piece removed. (6) Remove one inch of insulation from each end of the replacement fusible link. (7) Spread the strands of wire apart on each of the exposed wires (Fig. 10 example 1). (8) Push the two ends of the wire together until the strands of wire are close to the insulation (Fig. 10 example 2). (9) Twist the wires together (Fig. 10 example 3). (10) Solder the wires together using rosin core type solder only. Do not use acid core type solder. (11) Center the heat shrink 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. Fig. 9 Fusible Link Chart Fig. 10 Wire Repair 8W - 4 WIRING DIAGRAMS .

(12) Secure the fusible link to the existing ones to prevent chafing or damage to the insulation. (13) Connect battery and test all affected systems. WIRING REPAIR When replacing or repairing a wire, it is important that the correct gauge be used as shown in the wiring diagrams. The wires must also be held securely in place 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 of side of the wire. Make sure the tubing will be long enough to cover and seal the entire repair area. (4) Spread the strands of the wire apart on each part of the exposed wires (Fig. 10 example 1). (5) Push the two ends of wire together until the strands of wire are close to the insulation (Fig. 10 example 2). (6) Twist the wires together (Fig. 10 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 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 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. 11). (4) Position the connector locking finger away from the terminal while pulling on the wire to remove the terminal from the connector (Fig. 12). (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 into the proper cavities. For additional connector pin out identification refer to the wiring diagrams. (8) Insert the connector locking wedge into the repaired 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 and remove six inches of tape from the harness. (4) Stagger cut all wires on the harness side about 1/2 inch apart (Fig. 13).
