There is a fuse in the under hood fuse box that is for the rear of the truck. I believe it’s 29 or is it 19. I can’t remember.

01 f-250, Standard
Rev tech 4" lift, 37" military wrangler Mt tires
KC diy 66, Full force 160/100 and custom tunes from PHP
Banks intercooler and full 4" exhaust, Diy S&B intake
Diy quad feed, Hydra, Isspro boost, pyro, and fuel pressure
3/0 battery cables with military style terminals

Re: 02 F350 no brake lights. turn signals work

the 02 does not have an under hood fuse box.
in cab fuse box brake on off switch fuse is #34, 10 amp fuse.
if fuse is good, first thing to do is turn the 4 way flashers on off a few times, then check for brake lights. if the flashers were used and the switch hangs up the brake lights will not work.
next step is to ensure the brake light switch has power going into it, and power coming out when the pedal is stepped on. if you have power out of the switch, than your next step is to replace the multifunction switch (blinker switch) in the steering column.

If you want the moral high ground, make sure you're not standing on a hill of horsecrap.
