Speedometer and odometer not working , harness is ok and checked fuses and seem to be ok

What make , model and year vehicle . And what are you asking here ? What , odometer, cause the radio, speedometer, power What would cause these to stop working or could the odometer cause these to stop working ? It would depend on what controls them . A BCM - body control module ?

suspect you may have some sort of power issue. Check all fuses. May be a hairline crack in a fuse that powers the speedometer. If you can get a 12v light prove place negative of probe on car body and then put the probe pointy end on each side of each fuse to test each fuse .
google 12v probe.

fuse box, bad earth??????

if everything works when you jiggle the ignition... then its the ign switch try to see if wire harness plug is loose... if not have ign. switch tested then replaced..

the odometer needs to be rest.

dont b a **** fool and cut wires under your dash for some boom booms in your car buy the connecting harness they sell theres one for every make and model out there solves guessing and saves headaches... dont be a ******* buy the right parts

you may need a car electrician as these things need troubleshooting.the only thing you can do is by checking all fuses however if other gauges and indicator lights are working then the fuse for the inst. cluster is ok.the speedometer has a sensor installed on the transmission while the odometer gets signal from the ECU so these two problems need separate solution

You probably have a sporadic fuse failure - go in and replace the fuses linked to these functions with NEW fuses and make sure there is no corrosion on the fuse box connections - this should solve.

I had the same problem with my 90 daytona. The tach and the speedometer would work intermitantly. I took the whole gauge cluster out, and heated all the soldering with a solder gun to reflow the connections. It seems that this is a common problem with the connections cracking. You may not be able to see the cracks in the solder.

check for loose connection at the instrument cluster.
