You would be putting an OBDII ECU into a OBDI car. I think the OBDII cars might have an extra O2 sensor after the cat but I'm not sure. You could hook it up and pull codes with a 12v bulb going from ten to gnd in the diag box to see what, if anything, it will be unhappy about. The only thing I could see happening if it doesn't work right is poor gas millage. Do you already have this ECU or are you looking to buy it? If you are buying one, I would recommend just finding the older OBDI ECU to be sure that it will work.

1994 is actually OBD1 (OBD2 starts in 1996).Custom_V6_Limited_SE wrote:You would be putting an OBDII ECU into a OBDI car.

No problems running a 1992 K8, but your radiator fans don't have the correct connection with this ECU to get ON.
