All 4 O2 Heater sensors going at once?

Here is where it gets interesting.
If you find another feature is non functioning, best to take things one at a time. A schematic diagram covering the circuit for the oxygen sensors is practically required here.

I see... where cwhere download that? Main ford website? Lots of mud under this truck when I got it... maybe a rock or something hit one. Cant wait to start digging... haha.

Look at harnesses which may be laying on brackets, a/c lines, chassis etc. Fuses do not wear out and they blow for a reason. If a fuse fixes it, I would be prepaired for the fuse to eventually blow again in the near future.
BTW- I think you have a 6.2 engine in your F350. It is the only gas engine listed for your truck.
okay then! Wiring it is! And yes it probably is the 6.2 L. I think I might have put down what the expeditexpei used to own had. I'll definitely have some searching to do though! Thanks for all your pointers!

From what I can see from an earlier diagram ,they do share the circuit with other functions.
One of the things you will need to check, make sure the sensors are in there. sometimes guys alter things and figure they don't need them and either by-pass them or remove them. A good visual is a good place to start. Curious as to just what you find, thanks.

Whatever it is ,,,,,,,,,,,is common to all of them. Look for open ground wires too.

will definitely be looking for the culprit asap. Will update board when it happens, though, might take awhile to find wiring diagrams. I do know there's two ahead and behind cat... maybe youtube is in order!!!
