There no way you can use an OBD2 scanner with an OBD1 car. The interface is completely different and the protocol is completely different. I would strongly suggest you don't attempt it, because it appears from what I've found on the net that OBD2 works on 12volts, whereas your ECU works on 5volts. I think that if you attempt to connect them, you will probably damage your ECU.
I read somewhere that you CAN use an OBD1 Select Monitor on an OBD2 car because the OBD2 cars have both types of interface. But it's not going to work the other way around.
Here is some information about interfacing to OBD2. You can see that it bears no resemblance to the information presented on my website.
