sco350

Hi there guys, I'm actually a supra owner but need some help to upgrade to a 5 or 6 speed lexus auto box.I have tried searching but am having trouble finding wiring diagrams and the solinoid operation of the A350E,A650E or A760E auto boxes. After market black boxes can be programed to control the boxes but before that I need to know which solinoid does what and in which order.Also does anyone know, will the 760 gearbox bolt up to a 2JZ engine. Any help greatly received.
