I stumbled across the Japanese 1990-95 70 series wiring manuals today. 
Currently the best comprehensive manual out there for the 1990+ 70 series trucks is RM183E, but it is for the European 70 series not Japanese. The manuals I found cover wiring for the RHD Japanese versions including the motors Europe never got (2LTE, 1KZTE).
This is a major find for those of us with the LJ78 and KZJ78!!
They are now hosted as follows:
First link is .zip format (each book is multiple pdfs). Second link is the multiple .pdf format.
