I recently picked up an '86 g30 hi-cube with the 6.2 diesel. It's pretty cool, but I'm finding info and parts to be shockingly hard to come by.
The first thing I'm looking for is a wiring diagram and I CANNOT find one for a g30 diesel.
the previous owner was pretty careless and made some terrible modifications. He didn't like the two battery setup with one battery underneath, so he put both batteries behind the driver, and just bypassed the ignition switch with a battery isolator "master switch" built into the side of the driver's seat. I want to go back to the stock setup, but I can't find anything to reference in order to figure out what he changed.
I also can't find any body parts diagrams. The PO removed and discarded the underbody battery tray, and googling doesn't turn up a replacement. He took the lock cylinder out of the sliding door, dropped it down a crawfish hole and didn't bother to dig it back out, I can't find any information about that part online. Plus the latch isn't quite working like it should. I have no idea how to find a lock cylinder without a parts diagram. I might be wrong, but I'm assuming its going to be quite different from the front door locks.
The van in question has a body just like this:
