Default wiring trouble '86 g30

I recently got my hands on a beautiful 1986 g30 hi-cube, with the 6.2 diesel engine. Unfortunately the previous owner made some very questionable modifications.

For one thing, he changed the original dual battery setup. Instead of one battery under the hood and one under the vehicle, he put both in a battery box behind the driver's seat. In order to do this, he bypassed the ignition switch, so now there's a "master switch" battery cutoff switch build into the side of the driver's seat.

I want to put this thing back to stock, unfortunately I can't seem to find a wiring diagram for an '86 g30 diesel anywhere!

There's other stuff wring with the wiring, but lets just start here for now!

Thanks,
Azad

These old vehicle wiring diagrams were not very well documented like they are today. However, I do have them and can get them for you if you let me know what you need!

Body manuals have wiring diagrams.
