Default Checking OBD I trouble codes with a paper clip
So since my 95 is OBD I with the OBD II style connector, I need to know which pins to connect with a paper clip so I can read trouble codes? I'm pretty sure the SES light just blinks numbers and tells you codes on all pre-OBD II vehicles. So which is the diagnostic pin and which is the ground on a 16-pin interface?

nope. not on 94 either. Early 93's and under and the only ones. Your stuck needing someone with a good program or scanner to read codes for you.

Well I've got the 16 pin-to-USB cable so maybe I'll just try to find a free scanner program...any ideas?
