94 is OBD I and you can use a scanner like a tech 1 or 2 on it. OR use
a paper clip for engine and ABS codes. No trans codes.

Go to
http://www.troublecodes.net/GM/
and look at the picture of the ALDL connector.

Pin A is a ground

Ground pin B for ENGINE codes, key on engine off.

Ground pin H for ABS codes then watch ABS light and count the flashes.
