Default 1994 Brake pedal hard

I read a thread some time back that had over 1000 pages of comments on the cause and fix was for this problem. To be honest I was more confused after reading most of the replies than I was in the beginning. Obviously not all C4's are equal and what applies to one year does not apply to another.

first question, 1994/C4, OBD-I or OBD-II?

second, what pins to short to see the codes and clear them?

I will start with this and then take it from there..

94 is OBDI, but i think they started using the OBDII connector before 96? That's all I can add, I have a 93.

94 is OBD I. It has a OBD II connector. Connect pins 4 (ground) and 12 to initiate on board diagnostics (codes). It is a 16 pin connector.
