This is on my 81 Brat. No idea what it is, my manual doesn't identify it and it was disconnected when I bought the Brat. Anyone know what it is and it's importance?

Looks like it could be for cruise control.

Hmmm, possible.

 

My wife said she had a car that the cruise control was a button on the dash. My ignition is pooched and they mounted a toggle switch and a push button to start it and the spot for the start button looks like it was made for it, which could have been for that.

Figured out what they are, vacuum switches.
