If you are replacing an old ignition switch, you need to remove it first. Remove the screws holding the switch in place and gently pull it out. Be careful not to damage any wires in the process.

Step 3: Connect Terminal 1 to the Battery

Take the wire connected to terminal 1 of the ignition switch and connect it to the positive terminal of the battery.

Step 4: Connect Terminal 2 to the Accessory Circuit

Take the wire connected to terminal 2 and connect it to the accessory circuit. This is usually the wire that powers your radio or other accessories.

Step 5: Connect Terminal 3 to the Ignition Circuit

Take the wire connected to terminal 3 and connect it to the ignition circuit. This is the circuit that provides power to the ignition system.

Step 6: Connect Terminal 4 to the Starter Circuit

Take the wire connected to terminal 4 and connect it to the starter circuit. This wire is responsible for sending power to the starter when you turn the key.

Step 7: Connect Terminal 5 to the Ground

Take the wire connected to terminal 5 and connect it to the ground. This wire should be connected to a clean, bare metal surface on your car’s chassis.

Step 8: Connect Terminal 6 to the Engine Control Module

Take the wire connected to terminal 6 and connect it to the engine control module. This wire sends an ignition signal to the module, letting it know that the car is ready to start.

Step 9: Test the Ignition Switch

Now that you have wired the ignition switch, it’s time to test it. Reconnect the battery, turn the key, and see if your car starts. If everything is working correctly, your car should start without any issues.
