The 1970 Cougar Wiring Diagram

The 1970 Cougar wiring diagram is divided into several sections, each representing a different part of the car’s electrical system. The following is a step-by-step guide to reading the 1970 Cougar wiring diagram.

Engine Compartment Diagram

The engine compartment diagram shows how power flows from the battery to the engine and how it is distributed to the various engine components. The following is a breakdown of the engine compartment diagram:

Battery

The battery provides power to the entire electrical system. The positive terminal of the battery is connected to the starter solenoid, while the negative terminal is connected to the engine block.

Alternator

The alternator generates power to recharge the battery and power the car’s electrical system while the engine is running. The alternator is connected to the battery through the voltage regulator and the starter solenoid.

Distributor

The distributor distributes high voltage to the spark plugs to ignite the fuel in the engine’s combustion chambers. The distributor is connected to the ignition switch, which sends power to the coil and the distributor.

Starter Solenoid

The starter solenoid is responsible for engaging the starter motor when the ignition key is turned. The starter solenoid is connected to the battery, the alternator, and the ignition switch.

Ignition Switch

The ignition switch controls the flow of power to the various engine components. When the key is turned, power is sent to the distributor, the coil, and the starter solenoid.

Coil

The coil amplifies the low voltage from the battery into a high voltage that is necessary to ignite the fuel in the engine’s combustion chambers. The coil is connected to the distributor and the ignition switch.

Interior Diagram

The interior diagram shows how power flows within the car’s cabin and how it is distributed to the various electrical components. The following is a breakdown of the interior diagram:

Instrument Cluster

The instrument cluster displays critical information about the car, such as speed and fuel level. The instrument cluster receives power from the ignition switch and the headlight switch.

Headlight Switch

The headlight switch controls the headlights, the parking lights, and the dash illumination. The headlight switch is connected to the battery, the instrument cluster, and the ignition switch.

Rear Lights

The rear lights include the taillights, the brake lights, and the turn signal lights. The rear lights receive power from the headlight switch and are connected to the battery through the fuse box.

Heater Controls

The heater controls allow you to adjust the temperature and flow of air inside the car’s cabin. The heater controls are connected to the battery, the instrument cluster, and the blower motor.

Blower Motor

The blower motor circulates air inside the car’s cabin. The blower motor is connected to the battery, the heater controls, and the fuse box.
