Found this web site on original wiring
 

That's not much but as I don't have my own project, this is my way of maybe helping one or 2 members who MIGHT need the original wiring diagrams for Chevy cars & trucks. You will find them in .PDF and .JPEG on early (1920's) to "late" (1960) at this URL so here it is:

Just hope it was not already posted.
