Transmission Mode Indicator - A/T: Description and Operation
With the starter switch in ON or START battery voltage is applied to the automatic transmission mode switch and the A/T shift indicator control unit

shift indicator control unit applies voltage to the appropriate A/T shift indicator causing it to light up.
