eg86b16a2 your sig shows a 96-00 hatch that's why everyone thought you were obd2, your profile lists a '92 civic sedan, that's obd1.
did you get this figured out?
if not....
to get the codes on an OBD1 car, put a jumper in the little blue two pin plug under the dash on the passenger side. Should be either floating around if it's been used before or inside a housing secured to the outer wall.
Once jumpered, switch the ignition on (don't start it) the check Engine light will flash a code.
long flashes is the first digit, short flashes is the second digit.
second code's first digit follows first code if there is more than one.
check here for the meanings to the codes...
