Thanks I found the problem it was a sticking relay.
Here another one 1999 ford f-350 7.3L odometer works but not the speedometer. I tried to replace the sensor in the rear end didn't fix it. The truck has 4 wheel abs and from what I have read it uses the abs pick ups for the speedometer. HELP please
