Instead of pouring thru diagrams I simply use a 12V test light and turn the ignition on and off to find a fuse that does what I want. I just did it on my '01 F250 to power my GPS and XM from under the dash instead of cords strung across the dash to the 12V outlets. Then I found a circuit inside the driver's door that was hot-on-run and connected a micro-usb charger to it for my phone that I mount by the door latch/window control buttons. Saved another cord across the dash.
And even if you had your fuse number answer you'd have to test it the same way with a light or meter.
