Under dash and steering column wiring pics

[kjnmontana]

Howdy, I have a 1989 V3500 of which I’ve pulled the cab fuse block out, disconnecting all the lighting, ignition, wipers, etc. from it.
I’m now reinstalling the fuse block and was hoping there are some pictures/ diagrams that I can reference to correctly route everything back to where it should be.
I’ve already beat myself up for not taking some pictures, but the under dash wiring was a soup sandwich when I bought the truck, the main reason for removing it in the first place.
Wiring diagrams I have, routing pictures or images would be greatly appreciated.
Thanks KJ
