Dash button question

[CeylonstonE9]

How many buttons I should have on this? I bought this later one. My car didn't have one.
Car is 72 3.0 cs. I am getting this dash fixed.

1 round hole is open 2 are close. Should I get them opened? Please give me an advise.

I am assuming that square hole is not stock so I will get that one filled.

Rectangular hole is for later window circuit breakers.
round hole for rear defrost and
another for fog lights and another for driving lights

So I need all those round holes so I open those closed 2. I don't know why 2 of them are closed. Is it because this dash piece is for later E9 ?

you have fog lights?

Only open what you need, normal is just one for rear defrost.
