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!
