Speedometer Not Working - Speedo and Fuel Gauges Jumping Around

Yes it will work however your truck will show the mileage from the junk yard truck because the mileage memory is inside the gauge cluster. These 03-06 Silverados are bad about this kind of problem, it's usually caused by failing stepper motors inside the instrument cluster. Each gauge has a motor that controls it's needle movement and when the motor goes out the gauge will either stick, jump around or die all together.
