FX3 upgrade from 1990 to 1992

[sevensixers]

I upgraded my fx3 shocks and control module from 1990 to 1992 setup. I have brand new shocks and a used 1992 control module. I keep getting fault codes 14, 31, 32, 33? I have removed the actuators to verify operation and they do work when the ignition is turned on, so they are trying to find the end stops. I checked that the shock gear is 5mm higher than the mounting ring on top of the shocks. The shock gears rotate freely with no binding. I tried swapping actuators around and no change. I?ve tried to clear the faults by grounding the C pin on the ALDL plug. Does anyone have any ideas of what else to try ? I thought it would be a direct swap with no issues, but I should have known better !!! Any help to get these faults cleared would be greatly appreciated !!! Thanks gang !!!
