Checking for error codes, engine diagnostic
 

What is the process by which you extract ECU codes from a 99 1.6l? Which points are connected in the little black diagnosis box in order to retrieve them. Anyone have a code list with the definitions?
On my rx-7 I use the little diagram on the lid of the diagnosis box and connect the TEN and GND terminals but none are marked on the protege. Any ideas?

Thanks!
