The tabs hold the wires for the switches in the dash.
If you squeeze the tabs together with a pliers, you can push them inside.
You can cut an access hole as shown in the picture. Best to leave those 4 mounts, but you can do what works best for you.
Best to leave a rim around the outer area for mounting a cover plate. Again what works best for you.
All the wires coming out the cutout are extra ones I installed. Nothing in the way back there, just use common sense and don’t cut to deep.
Sure makes it easier for mounting switches in the lower row.
Good Luck.
