That's not a diagram, it's a book you're asking for. If you need something specific, we might be able to help you out. If you want the complete wiring schematics, I'd suggest https://www.ford-trucks.com/forums/1...s-members.html

Here is a version I keep on my site. It is for an '02 but should be identical for yours. I have bookmarked it into sections to make use easier.

careful with the 02 and 03 being the same comment....i think there are some differences such are wire color codes and some options....double check everything you come across before you tap into your pcm wire to steal power for some extra lights!

WOW, thanks guys. I was going to buy the wiring manual for my truck, but you just saved me $70.

Actually I'm just interested in what wiring and circuitry is fed from that fuse and why the owner's manual does not correctly identify what the fuse actually controls.

Welcome to FTE!

I'd suggest starting a new thread with your particular situation so we can focus on it. Necroposting on this thread obscures your needs.
