There should be a sensor on the tranny itself that just goes to the trans computer as I mentioned. On the speedo cable in the xfer case, I believe on a 1990 its just the cable to drive the speedometer. If you think about it the trans computer needs to know how fast the tranny output is turning and not how fast the vehicle is going, since that can change depending on the xfer case being in hi or low.
