1995 or 1994 coil?

The 1995 and 1994 coils have diffrent part numbers. I have a 1994 computer and 1995 optispark. Which coil should I use?

My car has had all kinds of problems and I have been running the 1994 vintage coils. I am wondering if this is part of my problem.

No, 1993-1995 are dual connector and 96-97 are single.

94 and 95 coils are exactly the same (same part number). 93 is a different part number.
