Fuse Box Diagram For 1991 Buick Park Avenue Ultra?

I need to obtain a fuse box diagram for my '91 Buick Park Avenue Ultra. There was no fuse panel cover when I obtained the vehicle nearly two months ago, and I have no idea what fuse controls what, nor what type of fuse goes where. Can anyone here tell me where I can get such a diagram?Fuse Box Diagram For 1991 Buick Park Avenue Ultra?Any luck with a local salvage yard?
