Hi. Here is a question I bet no-one has EVER asked!! Where do I get the proper pinouts for this ECU ?

As far as I could figure it came out of a '97 Crown UZS157, gen2 - 1uzfe non-VVTI, no immobilizer. 34/22/16/28pin.
I found a bunch if diagrams but all are different to mine... or did i miss a class somewhere?
It's in an old-school ramp truck Isuzu NQR. When I bought it, I drove it 250km home with an SUV strapped to its back. It did great! I took it on good faith that the ECU got enough feedback from the engine to shut it down if anything went wrong. The guys that did the swap, butchered the harness and wrapped their mess in sticky-tape.
The thing works, sort-of but the speedo cluster is not hooked up. None of the things like O/D or the pattern selector even exist.
I really would like to get all the necessary things sorted with its own ECU rather than changing to an aftermarket engine controller. Point me in the right direction, please!
