The 1994 through 1996 module years uses the similar style ecm, using a 4 connector terminal for the ecm. The 1994-95 ecm numbers are either 16181333 or 16188051. This is the OBD I ecms, using flash proms instead of the conventional removable eprom of the 1992-93 LT1. In 1996 the ecm numbers changes to either 16214399 or 16242921, this is the first true year of the OBD II systems

If your Opti is vented, you have 95. If you have a non vented Opti, you have a 94.

I sent you the links where I got this info.
