I guess my 93 F350 has two fuse panels. the manual refers to a power

OK, where the hell is it? I hooked up my 24,000 lb. trailer and lost

I don't know on a '93, but on a '09 there is the underhood fuse box
(BJB) near the brake MC and the junction box (SJB) in the cab in the
passenger side footwell behind a trim panel.
