90-91's are obd-0=good for crx.
look at header-1 wire 02 sensor, tells you it is obd-0, distributer plugs are cream colored not grey.(grey are obd-1)

And the plugs are round as opposed to square/rectangle. Alos on the back of the block theres an additional sensor, if you run OBD-0 you wont need to worry about this extra sensor. If you can see hte ECU and there's a little round window on it, it's OBD-0, thats how you can read hte codes it may send.
