Well in search of a wiring diagram for the back of the fuse panel I ended up just pulling mine out. I didnt want to tap a fuse for something I was going to keep I'm my truck and wanted to wire it up behind the panel. This isn't 100% but I got most of them in my short time befor work. This is the best way I could see doing this. I have a 2002 Limited 7.3L 2wd.

This is a pic of the sticker that is on the side of my fuse panel

Here are some diffrent views of it

 

I went back in the fuse panel (central junction box) and got a better list of where things are.

Here is a drawing of the front and back views.
