I have a 1995 S-10 2.2 liter truck. The brake light on dash remains on after releasing parking brake. I have disconnected the wire to the parking brake and the master cylinder but the light still remains on. I have tried to determine the diagnostic trouble codes per the Chilton manual, but the manual only refers to the '94 data link connector which is labeled with letters (vs. the '95 model which is labeled with numbers).
How can I tell which terminals on the '95 model need to be grounded to reveal the codes?
