switch on back of tach
I am sorry in advance for this weird ( I hope not stupid) question.
I have a 69 Z with the factory tach, clock in the center and then the speedo on the left along with the factory console with gauges.
Does anybody know what the slide switch on the back of the tachometer is for? You see it if you look at the back of the instrument panels from under neath laying on the floor.
Just wondering what this was for.
