Default ECU codes on an ef with b16a

how do you check for ecu codes on a 89 hatch with a b16a ecu.. like where is the plug that you put a wire into so the check engine light blinks out a code?

pull the cover off thats over the ecu, the jdm ecu has the light in a diffrent spot, and you cant look at it with the cover on, unless you drill a hole in the cover over where the light is.

I had the EXACT same issue with my newly acquired CRX. Remove the cover...the light will be on the bottom as if the cover or ECU was upside down.
