Where is the vats system on a 1977 cutlass supreme?

On a 1977 Cutlass Supreme, the VATS (Vehicle Anti-Theft System) is not originally equipped, as this system was introduced in the late 1980s. However, if you're referring to the vehicle's ignition system or anti-theft modifications, check the ignition switch and wiring near the steering column. For any aftermarket VATS systems, their location may vary based on installation. Always consult a repair manual or a professional for specific guidance on modifications.
