Default Under Hood Fuse Panel Diagram

Anyone have the under hood fuse panel diagram that shows what fuse is for what. I have a 99 silverado 5.3L. I have searched and searched but can't find one. I forgot to get it when I purchased the fuse box and harness. Thanks!

1FASTGTO - Thanks a lot, that will help.

John - I think it does have them on the cover, I forgot to get it from the junkyard when I got the motor and the junkyard is 300 miles away. If you don't mind some pics of the cover would be nice too, if the labeling will show up in the pics. Can never have to much information.

Thanks for the info.

Sorry I tried to get as close as I could without having to add a million pics. My cell phone isn't the best but I got all of the fuse box at least.
