Where is diagram for diy auto repair?

Fuse box diagram under the hood/2001 Chevy S10.
I have consulted Hayes and Chilton to find a diagram of the large fuse box and fuses to no avail. I need to know what fuses control what before checking for weak fuse. Also this is handy info to have for diy repairs. Any help would be appreciated.

On the inside of the fusebox cover is the diagram also in owners manuel.
