HOW TO USE THIS MANUAL B This manual provides information on the electrical circuits installed on vehicles by dividing them into a circuit for each system. The actual wiring of each system circuit is shown from the point where the power source is received from the battery as far as each ground point. (All circuit diagrams are shown with the switches in the OFF position.) When troubleshooting any problem, first understand the operation of the circuit where the problem was detected (see System Circuit section), the power source supplying power to that circuit (see Power Source section), and the ground points (see Ground Point section). See the System Outline to understand the circuit operation. When the circuit operation is understood, begin troubleshooting of the problem circuit to isolate the cause. Use Relay Location and Electrical Wiring Routing sections to find each part, junction block and wiring harness connectors, wiring harness and wiring harness connectors, splice points, and ground points of each system circuit. Internal wiring for each junction block is also provided for better understanding of connection within a junction block. Wiring related to each system is indicated in each system circuit by arrows (from__, to__). When overall connections are required, see the Overall Electrical Wiring Diagram at the end of this manual.

B HOW TO USE THIS MANUAL[N]System Outline Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW. When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows through the rear lights warning light to TERMINAL 4 of the light failure sensor. Stop Light Disconnection Warning When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the disconnection and the warning circuit of the light failure sensor is activated. As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lights warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning circuit on and holds the warning light on until the ignition SW is turned off.

BThe Current Flow Chart section, describes which parts each power source (fuses, fusible links, and circuit breakers) transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully understood.

HINTWIRE COLOR AND TERMINAL NUMBERIn some parts of the instrumental panel wiring harness, the same wire color (i.e. SB: Sky Blue) is used for all the wiring to a specific connector. In order to identify the wiring, the terminal number is printed on the wiring. Install the wiring to the connector position with the same terminal number. Some early production Vehicles may not have these terminal numbers printed.

E GLOSSARY OF TERMS AND SYMBOLSBATTERY Stores chemical energy and converts it into electrical energy. Provides DC current for the autos various electrical circuits. CAPACITOR (Condenser) A small holding unit for temporary storage of electrical voltage. GROUND The point at which wiring attaches to the Body, thereby providing a return path for an electrical circuit; without a ground, current cannot flow.

HEADLIGHTS Current flow causes a headlight 1. SINGLE filament to heat up and emit light. A FILAMENT headlight may have either a single (1) filament or a double (2) filament

CIGARETTE LIGHTER An electric resistance heating element.

2. DOUBLE FILAMENT

CIRCUIT BREAKER Basically a reusable fuse, a circuit breaker will heat and open if too much current flows through it. Some units automatically reset when cool, others must be manually reset. DIODE A semiconductor which allows current flow in only one direction.

HORN An electric device which sounds a loud audible signal.

IGNITION COIL Converts low-voltage DC current into high-voltage ignition current for firing the spark plugs.

DIODE, ZENERA diode which allows current flow in one direction but blocks reverse flow only up to a specific voltage. Above that potential, it passes the excess voltage. This acts as a simple voltage regulator.

LIGHT Current flow through a filament causes the filament to heat up and emit light.

PHOTODIODE The photodiode is a semiconductor which controls the current flow according to the amount of light.

LED (LIGHT EMITTING DIODE) Upon current flow, these diodes emit light without producing the heat of a comparable light.

DISTRIBUTOR, IIA Channels high-voltage current from the ignition coil to the individual spark plugs.

METER, ANALOG Current flow activates a magnetic coil which causes a needle to move, thereby providing a relative display against a background calibration. METER, DIGITAL Current flow activates one or many LEDs, LCDs, or fluorescent displays, which provide a relative or digital display. MOTOR A power unit which converts electrical energy into mechanical energy, especially rotary motion.

FUSEA thin metal strip which burns through when too much current flows through it, thereby stopping current flow and protecting a circuit from damage.FUEL

FUSIBLE LINK(for Medium Current Fuse) A heavy-gauge wire placed in high amperage circuits which burns through on overloads, thereby protecting the circuit. The numbers indicate the crosssection surface area of the wires.

M

(for High Current Fuse or Fusible Link)


ERELAY Basically, an electrically operated 1. NORMALLY switch which may be normally CLOSED closed (1) or open (2). Current flow through a small coil creates a magnetic field which either opens or closes an attached switch. 2. NORMALLY OPEN SPEAKER An electromechanical device which creates sound waves from current flow.

SWITCH, MANUAL 1. NORMALLY OPEN Opens and closes circuits, thereby i it th b stopping (1) or allowing (2) current flow.

RELAY, DOUBLE THROW A relay which passes current through one set of contacts or the other.

2. NORMALLY CLOSED

RESISTOR An electrical component with a fixed resistance, placed in a circuit to reduce voltage to a specific value.

SWITCH, DOUBLE THROW A switch which continuously passes current through one set of contacts or the other.

RESISTOR, TAPPED A resistor which supplies two or more different non adjustable resistance values.

SWITCH, IGNITION A key operated switch with several positions which allows various circuits, particularly the primary ignition circuit, to become operational.

RESISTOR, VARIABLE or RHEOSTAT A controllable resistor with a variable rate of resistance. Also called a potentiometer or rheostat. SENSOR (Thermistor) A resistor which varies its resistance with temperature. SWITCH, WIPER PARK Automatically returns wipers to the stop position when the wiper switch is turned off.

SENSOR, SPEED Uses magnetic impulses to open and close a switch to create a signal for activation of other components.(Reed Switch Type)

TRANSISTOR A solidstate device typically used as an electronic relay; stops or passes current depending on the voltage applied at base.

SHORT PIN Used to provide an unbroken connection within a junction block.

WIRES Wires are always drawn as (1) NOT straight lines on wiring CONNECTED diagrams. Crossed wires (1) without a black dot at the junction are j not joined; tj i d crossed wires (2) with a black dot or octagonal ( ) (2) SPLICED mark at the junction are spliced (joined) connections.

SOLENOID An electromagnetic coil which forms a magnetic field when current flows, to move a plunger, etc.
