When I picked up my 83. I dug up a couple of manuals from fleabay. Search for "Mitsubishi Truck Service Manual". The service manual will have the wiring diagrams. You can also search for "Dodge Import Parts Manual" for the complete parts manual.

I have both of these manuals. One of these days, I'm going to get my manuals scanned in and posted online. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />
