Actually, the OBD2 style connector under the dash does not make the vehicle OBD2. 1994 LeSabres were still OBD1. The '94 & '95 GM vehicles with the newer connector do not have the class 2 data terminal and wiring. The '94 & '95 Corvettes, and 1995 F body cars all have the OBD2 style connector below the dash, but are not OBD2. Actual OBD2 GM cars and trucks came along in 1996.
