Hi,
To my knowledge there is nothing currently available in the public domain. The ECU pinouts are very similar to the 95 Supra 2JZ-GTE with some minor differences (available on the MKIV site). A continuity meter and a bit of time will tell you what the rest of the pins do.
I also have never found any Aristo diagrams that cover the remainder of the car, like the cowl and dash looms. (You'd be able to get something off the US toyota tech site but that involves subscriptions etc..).
If you have any specific questions as to specific pins on a specific plug I can go through my notes (but please don't ask for the notes).
Mos.
