obd1 to obd2

can you just get a obd2 computer and put it in a obd1 car? will it hook up of do you have to do something to the harness

all you have to do is change knock sensors

What about the rear 02s?

obd1 to obd2??? are you sure you dont mean the other way around

obd2 to obd1 all you do is change the knock sensor

obd1 to obd2 many changes, the obd2 pcm uses a crank sensor, rear o2 sensors, different timing cover crank hub plus many other differences

The crank sensor is only used on 97s.
