It doesn't matter if you have a scanner that reads both OBD1 and OBD2. You have to use the OBD1 connector (if it has both) and connect the pins like pictured in the link I posted. There is nothing that you can just plug right up and read the codes unless you modify a scanner to work.

Ahh..it helps when he told us what Cable he was using.. I'm trying to break down all the wiring and ****..lol
With the 1995's you have to use a OBDI Cable with a OBDII Connector on it..like a few of us have mentioned.
The only way to use a OBDII Cable is if you have a OBDII Engine.

So the GM techs at the dealership had to make a jumper set up to read the '95 cars?
What did they do?
I think there is some issues with the ALDL wiring, i would guess that some other stuff is hanging on that wiring creating the issue. All that needs to be removed and then proceed.

Most places that make the Scanners made the special Cables when the 1995 Models came out. They still have them available or could make them considering the amount of 1995 cars out there.
1995 Cars are wierd, I haven't seen 2 that were wired the same..lol
