Wow now this will be reviving an old thread! Anyway i'm googling around to see if my 2000 Corolla supports OBD2, there is a port to the right under the steering column and also one in the engine bay. But im not 100% sure that the car actually supports OBD2, im kind of afraid to plug in this OBD2 adapter i have in case if it doesn't support OBD2 it might break something. If anyone could shed some light on this that would be great.
