Speedometer Issue 97 Xj Dakota Digital Box
The photo is me traveling around 60-65 in 5th gear, of I hit a bump in the road or burp the throttle the spedo will bounce back and the shift light will stop indicating. I tried swapping out the digital box and this was not the issue. I checked the ground wires and found no continuity issues or build up in dirt. What should I troubleshoot next? This issue does not seem to exist when 4x4 is on only in rwd. The issue isn't constant but is persistent. Airbag light goes on and off long before the speedometer issue started.

It's the connections behind your cluster. Remove the cluster, clean everything up with some electrical cleaner and make sure all of the contacts are good. Look for any loose or broken wire connections and plug it back in. I put a couple of shims on the connectors of mine to keep it more snug when reinstalling it. Mine did the same thing when off-roading or hitting a hard bump. The speedo would go to 0 and the airbag light would come on. If you want proof of the loose connection, next time it does it, give the top of the dash over the cluster a good whack with the palm of your hand and they will come back to life until you hit the next bump.
