Cracked dash circuit board? I don't know how this could happen, and I doubt it, but hang in there.The PCM is seeing what it needs to run the truck. This includes RPMs and speed. The signals just aren't getting to the cluster.

This is for a 2001. I do not have a manual for the 99.

Do you have normal startup warning lights that go out as they should?
- Do the SERVICE ENGINE SOON, battery, safety belt, brake, or ABS indicators prove out?

OK, I have to go to bed, but if your normal dash idiot lights do not light up, the manual says it is a fuse. From there we could go further.

If the connection appears good, you need to verify voltage at the harness, Use a wiring diagram for your truck with KEOO. This is for a 2001:

Here's B5 for a 2001, and I am done.

Yes VERIFY the instrument cluster printed circuit connector is fully seated. If so, INSTALL a new instrument cluster. REFER to Instrument Cluster in this section. TEST the system for normal operation.
