For reference, "83 and '84 Celica EFI wiring is the same. '85 EFI is different but it is the same as the '85 truck(body wiring is completely different). I have an '84 FSM that I'm copying the Wiring diagrams and EFI sections to go along with my '83 setup when i sell it. I can make you an extra set for the price of copies and postage if you want.
