Connections in the Ignition Switch Wiring Diagram

Purple Wire: Starter Solenoid

The purple wire carries electricity from the ignition switch to the solenoid on the starter motor. When the ignition key is turned, the solenoid engages the starter motor, which turns the engine over.

If you experience issues with starting the engine, the solenoid may be faulty or the connection may be loose. Check the wiring and the solenoid before replacing any components.

Pink Wire: Accessory Power

The pink wire carries electricity from the ignition switch to the accessories in the vehicle, such as the radio or interior lights. When the ignition key is turned to the “ACC” position, the accessories receive power without starting the engine.

If the accessories are not receiving power, check the wiring and the accessory components for any damage or loose connections.

Yellow Wire: Ignition Switch

The yellow wire carries electricity from the ignition switch to the starter solenoid and the distributor. When the ignition key is turned, the electricity flows through this wire to activate the starter motor and distribute spark to the engine.

If the engine is not starting or running smoothly, check the wiring and the distributor for any issues.

Brown Wire: Tail Lights

The brown wire carries electricity from the ignition switch to the tail lights on the truck. When the ignition key is turned, the tail lights receive power.

If the tail lights are not functioning, check the wiring and the tail light components for any damage or loose connections.

Red Wire: Battery Power

The red wire carries electricity from the battery to the ignition switch. When the engine is running, the alternator charges the battery and provides power to the vehicle’s electrical components through this wire.

If the battery is not charging or the electrical components are not receiving power, check the wiring and the battery for any issues.

Green Wire: Distributor

The green wire carries electricity from the ignition switch to the distributor. When the ignition key is turned, the electricity flows through this wire to the distributor, which distributes spark to the engine.

If the engine is not starting or running smoothly, check the wiring and the distributor for any issues.
