Electrical Issue. Please help.
I have an 03 4x4SD with the 6.0.
Last week the turn signals, back up sensors and the over head trip stopped working. So after digging around, it turns out to be the fuse under the hood.
now that I have replaced the fuse the backup sensor will activate when the truck is in any gear, even in park. I bought a Chiltons book, but the electrical schematic is sketchy at best.
Does anyone have a better exploded view of the electrical system, particularly the items in question so I can troubleshoot this?
Thanks.

Nice link. I'll add that one to my bookmarks 
It doesn't show me how the 3 items are linked together if at all. There has to be an exploded view of the entire electrical system somewhere.

So I ended up taking it in and a $100 dollar fuse later they "fixed" the problem. They also made sure to note all the aftermarket stereo stuff to the ticket to pass the trouble on to someone else.
It went about 2 weeks with no issue and popped the fuse again. this time I spent some time on it. It is the secondary Ignition circuit. Again it's the turn signals, back up sensors and the over head trip computer.
It's at a dead short so I have been unplugging different parts of the circuit to see what is grounding out.
I still can not find a diagram that would show what is all on this circuit.
Any thoughts?
