OK, got my first XJ, its a 2001 Limited, but the front axle is a D30 pre 91 W/disconnet (but no vac lines are connected), previous owner has shimmed or done something to the vacumm disconnect fork cause 4x4 works great, problem is the ABS speed sensor is disconnected from hub and zip tied up and out of the way (I can't find a place for them to connect to the hub knucle), the VSS in the TC looks newer and in good working order, I do have a CEL code p0500 (no singnal from VSS) my speedometer stays at 0,

Q: Does the ABS speed sensors have anything to do with speedo not working?????
