The boost monitor lights were an option in 1980 and 1981.
The console was different in 1980 and 1981.
The switch for boost light intensity was different for 1980 and 1981.
In 1980 the switch was on a trim plate residing were the map pocket
would have been. In 1981 that whole area is moulded closed, the
light intensity switch is back by the console lid (front).
One of the most common misconceptions is that 1980 and 1981
were nearly the same, they are in fact very different.
Over the years many swaps may have occured, this further complicates
understanding of the two years.
