At least that is how most of our electronic transfer cases with these days.

Makes sense, but the issue im seeing is that in the J shift models with multi mode they have a switch/sensor on the shifter or transfer case I would assume that recognizes the different shift placement to engage the CDL. On the 01-02's its not automatic. I bring this up because I would think the OP's problem lies in that area of his wiring the ECU to the older style J shift switch/sensor for CDL.
