Diagrams are Greek to me, so I might as well take a swing for all 3 years, hope my new wiring guy can decipher which harness I actually have, since Toyota learned how to do things the Ford way: use whatever you got until it's gone, hope no one notices. I have a Japan made, Japan release/sold 82 BJ44.. 2B engine, 24 volts.. I could also use an interpreter to get a better idea of production date.. Frame is K-BJ44V-KCY and serial is BJ44-006162. Knowing if this is before or after April(I think) could help a lot for parts down the road.. If there's a book out there that'll have what I need, any info greatly appreciated.
