Duster Dash Mystery- Name that missing item.

In Canada, many dealers were charging extra and installing "econometers" that simply lit a light when you stepped too hard on the gas.

If I remember correct it was a vacuum switch that would light the left front fender mounted turn signal indicator.

I ran into one of those back in the 80's while working at the dealership, was a surprise when it light up on a road test.
