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.
