What is the Location of VATS module on a 1986 Corvette?

There's no VATS (Vehicle Anti-Theft System) module as a separate, identifiable unit in a 1986 Corvette. The VATS system in those vehicles is integrated into the ignition switch itself. The passlock resistor inside the key is what the system reads to determine if the correct key is being used. There's no separate box or module to locate.
