Where is the radio/headunit fuse on my 2004 ford e450/thomas?

[decker1]

Thank you all for your help! I sincerely appreciate this for . I was installing a new head-unit in my 2004 ford e450 Thomas built when i accidentally made a few sparks via the positive and negative. looks like i blew a fuse. I have been looking with no success for this fuse, and there are just way too many (in different sizes) to try/eliminate.
Does any one know and care to share where this fuse might be? I would figure this would be in the fuse panel above the drivers head.

Bonus: Im also looking for the fuse to the interior light INSIDE the fuse box above the drivers head ironically. Although not as important as the head unit one Thanks!

The radio itself should have an inline fuse or a fuse in the back of the radio.
If that's the case you will have to pull the radio to get to either one.
That's the best I can do for an e-450?

In this case it isnt the actual radio, but rather the connections that lead from the radio. Which means I am looking for a fuse part of the cab itself

Send a pic of your cab steering wheel area.
Don't know the 450 but am around many.
Someone else should be along shortly.
The interior stuff is usually under the left of the drivers leg and anything motor wise is under the hood.
As a matter of fact try to PM mr4bttahoe I think is it? He is usually posting pics for an e350 goshen.
He can probably tell you exacts

Thanks! As soon as i get home I will. I have a feeling its in above the driver where the relays are. There are interior cab light fuses here too. However you cant tell which fuse is blown because all the fuses are encased in a metal shell.

Why are you playing with wires without unhooking the batteries?
Most manuals say disconnect the battery. ANd some say wait 15 min for the computer to discharge?
Most of that is for safety but some is so you don't blow your computer or muck up a related relay in the computer that can only be fixed by replacing the whole computer.
Battery pos off is a definite when I do anything on the wiring. Bus or chassis and I don't have a computer
