I apologize if this info is somewhere else, I searched and could not locate what I needed.
I am taking a 3rd gen 3S out of a 97' (ST ODB2) celica and putting it into my 94' (GT ODB1) celica. I have swapped a 3S into a 94' before, but not a 3rd gen and not into a ODB2 car. Is there any differences in wiring in the engine to an ODB2 car vice the ODB1 car? Will I need to rewire anything or will this be plug and play? Thanks!  This...  In to this....

from my experience so far, there are slight differences in the chassis side wire harness between obd I and obd II cars. Most notably is the number 12 pin on the EA1 connector. The usdm obdII cars have pin 12 as a ground, whereas the 3sgte harness needs that been for the aux fuel pump relay. I do not believe obd I cars have this problem
