Originally installed on 1968-69 Camaro and 1968-72 Nova models with the optional console gauge package. This unique indicator helped the driver to make sure there is fuel in the tank. As the tank level reached the 2 gallon level this module transmitted a pulse through the fuel gauge and activated a lamp indicating near fuel starvation for the car. Replaces original GM part number # 1596409. Officially Licensed by General Motors. Includes instructions for Camaro and Nova applications. Made in the USA!Long out of production it is once again available to make the restoration of your 1968-69 console gauge set truly complete. May be used for replacement of existing defective modules or when converting vehicles from no gauges to factory gauges.
