Sorry, I can't help in the repair of the truck..... There's no telling what got smoked from this boneheaded install.
But this is what I'd suggest;
Get a written statement from the truck repair shop as to how this plow was installed to a vital operational circuit of the truck with a higher amp fuse, With this is being what caused the needed repairs.
Take a copy of this statement and the repair bill to the plow dealer and explain the situation level headed, If the plow dealer declines to take care of the repair bill caused by their stupidity, Take them to small claims court.
I'm not sure about your Ford, But both my Jeep and GMC have a main positive power supply post just outside of the under hood fuse panel. THAT'S where any added external accessories should be powered from with the appropriate fuse holder or circuit breaker......
