So, what's your question? OBD 1 requires shorting 2 pins in the connector and counting the CEL flashes. Google can be your friend.

As Fleming said, need to short A to B on the ODB1 connector and count the flashes OR get a reader to determine what is wrong?

Hope Brian doesn't mind. We cannot debug over the internet and you really have no choice but to do some homework if you are going to figure this out? Or, shell out some coin, and take the car to a shop?

There are no vacuum hoses of any kind that connect directly to the computer.

Are there 2 bundles of wires plugged into it, 2 big connectors with lots of wires?

Mine doesn't either but I was reading on the internet [and you know everything on the internet is the truth . . . !] but "some" gbodies have a baro sensor line coming out of the ecm that runs up behind the glove box. If he has a vaccuum line coming out of his ecm, that has to be what it is?

Or it's the completely wrong ecm for the car and that is the problem?
