dead pedal, no instrument panel problem

I have a '00/'01 (unsure) f550 with a 7.3 and around 150k on the motor. the o/d switch had been acting up. on the way to the job the other day all was well until pulling into the job site. the accelerator pedal went dead and so did all of the gauges. now from reading i have found the dreaded problem of the o/d harness getting chaffed and shorting out. i did tear the steering column apart and did find this was a problem. however, it never blew a fuse that is typically associated with this problem. i have the p0221 code for the pedal sensor, have changed the fuse anyways just incase, but i still have no accelerator or gauges working. it will start with no problem. i unhooked the o/d harness and that didnt fix anything. i have checked voltage to all fuses i think are associated with this and i have power into the under dash fuse panel. but nothing works in the dash nor i have power to any wire in the accelerator pedal harness. is there something im missing or something else i can check? i know the harness needs repaired...but does it need to be hooked up for this to work? i cleared the code in the computer with my sct scanner and as soon as the truck starts it throws the code again. i had to go get another work truck and leave this one at the job site. please help and all help is appreciated.

I'd bet it's still a fuse....

Which fuse are you looking at? If it's an '00 or an "early" '01 it might be #19. Later '01's and above it's #45 (your 550 might be different too). But, I'd bet you've overlooked the fuse because 90% of the time that's what it's gonna be. Use a meter on both sides, wiggle them a bit, do it twice!

I looked at both fuses and changed them both. I'll look it over again after work tonight. Any other ideas?

Well, again,,, are those two fuses the ones you should be concentrating on in a 550?

Might be time to figure-out what year the truck is and go through the Owners Manual (if you don't have one -> Owner Manuals | fleet.ford.com )

well finally got it tracked down. the windshield had been leaking and when it would rain...the fuse box was getting water in it. this in turn fried the fuse panel and some module...not sure because i didnt pick it up or the repair bill.
