Found this on top of my heat/ac box behind the glovebox. If so what would it have controlled?

This.

Do you have a feedback Quadra jet? It’ll have some wires coming out if it of you do.

I just bought the truck, it has a junk Edelbrock on it and one of those goofy Accel coils on the HEI so it's been bypassed.
