Yeah Brian, The listed SLD for the Supra 2jzgte auto is the Type II, i believe this is an 8 wire version rather than the normal 4 wire SLD type 1's which are for manual cars. Though if you can live without cruise then IIRC you can still just use 4 wires as per normal.
The Aristo is listed as the Type T6 which as 16 wires, I'm led to believe it takes and manipulates signal feeds from all wheel sensors/Trac Ecu/Ecu/cruise to combat the Trac/cruise problem these things throw on some Auto Cars - the JZS147 being one such car :-(
There was a guy on Supraforums Aus that had managed to get them translated but no longer posts, I would also be interested in the Type II wiring if anyone has it for Future Reference, for for now its the T6 im hunting.
