How do you disable the theft deterrent system on a 1990 Camaro?

To disable the 1990 Camaro theft deterrent system (VATS), there are a couple of approaches.

1. Bypass VATS:

• Locate the VATS module, usually under the dashboard or near the steering column.

• Remove the VATS module.

• Connect the following wires:

- Wire 1 (purple) connects the ignition switch to the VATS module.

- Wire 2 (black) connects the VATS module to the starter solenoid.

- Wire 3 (white) connects the VATS module to the key resistor.

2. Bypass VATS with a resistor:

• Identify the resistance value of your key by checking the key resistor color code

chart. Each color code corresponds to a specific resistance value.

• Purchase a resistor with the same resistance value as your key.

• Disconnect the VATS module.

• Locate the connector from the VATS module to the ignition switch.

• Connect the resistor to the connector's purple and white wires.

• Reconnect the connector to the VATS module.

These methods will effectively bypass the VATS system and allow the vehicle to start without the use of a functional key.

*Note: Before performing any modifications to your vehicle, it's always recommended to consult a professional mechanic and refer to your vehicle's specific service manual to ensure proper procedures are followed.*
