Default 1989 Cherokee Pioneer 4.0 Rewire

Anybody know where I can find a full wiring harness for my Jeep?
Need to do a full rewire, this Jeep was previously owned by my father who has since passed so I am not getting rid of it.
The jeep is jerry-rigged to the max. I can either have brake lights working or headlights, radiator fan or windshield wipers, etc. There are also many things just do not work period including the radio, dash lights, blinkers, etc.
I want to rewire the thing from front to back and top to bottom. I have done some research trying to find a harness but all I can seem to find are universal harnesses like Painless.
I am fine buying one that is universal but I do not want to drop 600 bucks then be stuck with a lump of wires.
Also I need to find the 2 replacement fuse blocks (The one that goes in the driver side floorboard AND the one that mounts under the hood in the engine bay). Everything has been wired to the block that is on the drive side firewall.
Also also, If anyone can point me in the direction of a good wiring diagram or schematic of what should go where that would be much appreciated.

Thanks in advance

Before you go down a rabbit hole, you need to know that interior fan, blinkers, radio etc are supplied voltage by a pin on the ignition switch that is prone to melting.
