I have disassembled a t90 to the point of removing the head unit (shutter button/mode assembly) and the grip; however, I am dismayed to find that the service manual offers no schematic for the placement of wires as far as reattaching the head unit. There are six leads that need to be reconnected, and I was not able to note their placement before disconnection. If anyone knows where I could find this wiring pattern I would appreciate it.
