Does anyone know what plugs up where? 73 f100 under the steering wheel.



The junction box





Bad pictures I know.

 

That isn't stock.. your first clues shouldda been the ATC fuse, inline fuse, and cheap azz crimp connectors.

Be your own detective and trace the wires.

 

Hmmmm, never seen style that before....sorry

I could be wrong but I dought that it is stock. Is there fuses anywhere? Wait, ok, there is that one, you would want way more than one. Looks like someone removed the original and had a mo betta idea.

I think Fordification had some decent wiring diagrams online.

 

Someone butchered the hell out of your wiring. I know it looks stock because of the numbering and what-not, and maybe it was stock, but not on our trucks. Not that I've ever seen anyhow.

 

So the original fuse panel is missing? If so, your best bet would be to wire in a new one the correct way before a more serious problem arises

 

Agreed. The factory fuse panel looks like this:




I'd go over the entire electrical system with a fine-toothed comb and get it re-wired safely if it were me. Could use a factory panel/harness or one of the reproduction ones, but getting rid of those dangling wires, crimp connectors, etc. is probably worth doing, as is just figuring out what's going on with your power distribution for your own peace of mind.

 

If you have to re-do the box, I'd switch over to the blade style fuses. I'm going to do the same thing sooner or later, I'm not in any rush because mine isn't butchered...but wow yours is bad.

 

Thanks for all the tips guys. I have a few buddies and a case of beer coming over today hopefully I will be able to get this fixed!!

 

Well after two days messing around with the electrical system i don't think i can salvage anything from it. There was extension cords ran through out the truck. Does anyone have any suggestion on where to get a new harness.

 

Or it should looks like this? And here is a few other diagrams to look over.

bkaul I think that is a fuse box is for a 66-77 bronco also? It sure looks like the one in my 71 EB glove box.

But then again I think that bigger box I show is for a 76 truck and up? Sorry to cause any confusion tubtub.

 

Centech offers a replacement harness with Ford plugs and switches. It's less painless than Painless...

 

It would surprise me if Ford hadn't also used the same fuse block on other vehicles. My '74 has the smaller one I pictured, as opposed to the larger one. Not sure what year they switched.
