Roger, the other ECU was 1988 and earlier, for the LH2.2 Jetronic Fuel System. The 1989 and later ECUs are for the LH2.4 Jetronic Fuel System. They are not interchangeable. All LH2.4 ECUs will work fine in the 1989. The 948 is the latest version. The only ECU that will cause a problem is the ones from the cars with EGR systems, they will cause a check engine light, although they will work fine.
