well i dont know if theres a diff. to how to read the codes between obd1 and obd2 but i have a obd1 and all i do is go under the passenger kick panel and there should be a blue plug with only 2 wires just jump that plug with some sort of gauge wire, and turn on the key to on position and the cel should flash

long flash = 10
shor flash = 1

and thats it. hope that helps
