Fusebox ID

I have a 1978 F250 4x4 with a 460 in it. Based on what I've learned from this group, the 460 must've been swapped in by a previous owner. When looking at my fuse panel, it seems different from what I'm seeing in reference books and online as to what a fuse panel should look like in a 78 f-series. I'm wondering if maybe it was swapped in with the engine. Is that something you would have to do? Anywho, curious...can anyone ID what make and model this fuse panel would've come from? I'm trying to chase down a weird hazard flasher occurrence, and wondering if it's related. Hazards don't work, but my two blinker lights on the dash come on and stay on whenever I put the hazards on and step on the brake--but nothing happens outside aside from brake lights coming on when brake pedal is depressed (as it should).

That looks right to me. Here's a few screenshots from the 1978 owners manual.

That looks like an empty turn signal flasher socket in front of the fuse box just hanging there.

Makes sense to me, no flasher, then the hazards coming on solid with brake application. I recall another thread ... did you not have a flasher hooked up then? ... (Hazards Lights Issue - Ford Truck Enthusiasts Forums (ford-trucks.com)) ... you never actually answered if the flashers worked, now ... I was thinking you tried new flashers (there are two) but maybe I was thinking of another poster ... I saw 5851a's post above, it clicked. If that flasher terminal was not holding a good flasher for hazards when you were "testing", then the flashers were not getting any juice until you stepped on the brake, but the brake is a steady juice. It was "backfeeding" ... through the turn signal switch I'd say. Fuse box is right.
