Where I'll find a Scanner adapter conector and software for the diagnosis engine of Isuzu trooper 1995 3.2L DOHC?:)

This does not exactly answer your question, but it is the process I went through when I was asking the same question!

It shows photo's of the diagnostic connector on my right-hand-drive Trooper. Keep in mind that while the U.S.A. models had to support OBD-II from 1996 on, the Australian vehicles did not. Also there are some links to interesting sites about analyzers.

The relevance to you will depend on whether you have the older 3-pin ALDL (Assembly Line Diagnostic Link) connector, or the 16-pin OBD (On-Board Diagnostics) connector like mine.

The bottom line for me was that I could not find any adapters or software to suit my vehicle but I did discover how to display the trouble-codes on the instrument cluster CEL (Check Engine Light) - see Post #14 in the above link.
