Default 1991 f250 wiring harnesses

Hey all this is my first time on a forum of any kind so i hope im posting this in the right spot. I recently came into a 1991 f250 custom 4x4 manual 5.8l. The previous owner had bought a new fuel pump for the midship gas tank (there is only 1 tank on this truck). The new fuel pump and sending unit came with a non factory plug that does not fit the factory plug on the ford wiring harness also it has different colour wiring. (Spectra fuel pump). I know this and i know the proper combination of wires. My problem however is that the previous owner in an attempt to attach a new connecter, that would attach to the new sending unit connecter, cut and spliced wires from the tail lights all the way to the in cab fuse box. Surprisingly he managed to frankenstein it enough to make the truck run. I want to replace all of the wiring that was damaged but i need some more info and was wondering if anyone on here

A) has a new 1991 f250 4x4 5.8l wiring harness

(The one i need runs from a connector that attaches to another connecter at the firewall, The two are bolted togeather the second one going into the cab of the truck. The first runs from the firewall under the master cylinder down the frame on the drivers side it has connections for the brake distributer valve (not proper lingo haha), fuel pump, rear diff and tail lights.)

B) a fusebox and harness which i believe attaches to the previous harness i need

C) diagrams for these harnesses

D) proper name of mentioned harnesses

E) general info

Ive done alot of looking around and cant find the harnesses anywhere from scrap yards to kijiji any help is appreciated thank you.
