to the right of the button?

and also, can i remove the button if i'm installing th 32/36 dfev and getting rid of the vacuum stuff?

It is a fast idle switch that was part of the smog package. I have a 76 with a 32/36 and have removed it.
I'm sure some other members have a much more thorough explanation...

so it's ok to remove both the button and that box type thing to the right of it?

the "box" is the voltage regulator. Unless you're installing an alternator with an internal regulator you'll end up with a dead battery

[donerehart]

The box thing to the right is needed... The black button used to have another metal piece called a weber electrovalve underneath it (you can see the mounting spot with the two holes). The black button and what it is mounted to can be removed. I don't think you want to remove the regulator.
