In July 1999, Toyota began production of the seventh-generation Celica, with sales beginning late that year. This generation was assembled by Kanto Auto Works at its Higashi-Fuji plant in Susono, Shizuoka Prefecture, Japan.
Some vehicles are fitted with a factory amplifier installed behind the glovebox. Rotate both hinge stops inside the glovebox counter clockwise, then pull the hinge stops out to remove them. Lower the glovebox and look for the amplifier in the dash. If an amplifier is present then an active ISO lead is required.
