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! biggrin.gif

yup. My '99 st204 has a white/black wire at the pin 12 location, but the 3sgte harness needs a wire coming from the aux relay box in that spot. Luckily there is no problem with unpinning that white/black wire since it is only a ground. I posted a few photos in my swap thread if you need a better look, you can see the wire I'm talking about in one of the pictures:
