you will have to take it to a dealer to get the new one reflashed to your mileage. should cost a few hundred or less to get it done.
The mileage is stored in the BCM not the cluster, so you can replace the cluster without changing the odometer reading.
2000 Ford Expeditions with digital odometers are prone to the common intermittent odometer problem. That is, the odometer sometimes works normally and at other times the odometer display will be dim or completely blank. The problem is normally caused by defective solder joints on a printed circuit board on the back side of the instrument cluster. There are basically three options for repairing the problem: (1) Replace the instrument cluster with a new or rebuilt cluster (the dealer charges up to $600) (2) Replace the instrument cluster with a used cluster. While somewhat cheaper, used clusters are likely to have the same problem. In addition, programming of the replaced cluster and programming the ignition keys to communicate with the PATS (passive security system) located in the instrument cluster will drive the cost considerably higher, well into the hundreds of dollars including the cost of the cluster. (3) You can repair your own instrument cluster for free by repairing the defective solder joints. Several Ford forums have information about repairing this common problem. For those who would prefer not to spend a lot of time reading through years of forum posts, all the information needed for repairing odometers with this problem is available in a repair manual format at http:www.fordodometerrepair.com .
Check the IOD (Ignition Off Draw) fuse, and all of the incoming and ground connection in the instrument cluster.
There is no odometer cable. The odometer is controlled electronically via the vehicle speed sensor reading. The PCM converts this into an electrical signal and sends the signal to a drive motor located right behind your cluster face.
Mileage is stored in the PCM, so regardless if you change the cluster out for a new one or the sports package, it'll show the correct odometer reading
It is against the law for you to change the odometer reading. Ask the State Police (Highway Patrol) in your area what the procedure is. Be careful, there's something like a $10,000 fine for changing one. ----It is only illegal if the car is less than 10 years old and only if it is done with the intent of misleading someone to the actual mileage of the car. If you are changing the mileage on a replacement instrument panel to accurately show the actual mileage, it is perfectly legal. As to how to do it? There are some videos on you tube that show how.
It is the mileage that is actually on the car. If the odometer is replaced, the correct reading is written down. Add that to the reading of the replacment odometer and you have the actual mileage on the car.
It is against the law to change an odometer meter please
It is the odometer in kilometers, the first is in miles.
The exact mileage per year is the odometer reading at the end of the year minus the odometer reading at the beginning of the year. If you don't have the odometer reading from the beginning of the year, the next best thing is to subtract an older odometer reading from the reading at the beginning of the year, then divide the difference by the number of years between readings. Without any odometer readings from the past, the best you can do is to calculate the average annual mileage over the life of the truck, which is the current odometer reading divided by the truck's years of service.

The problem with Miatas is that the odometer memory is actually held in the electronic gauge itself. Therefore, if it needs to be replaced, the number will be the mileage as on the new odometer - 0. Or if you purchase a used odometer, it will display that mileage, not your original.My advice is that you purchase a used odometer, and that includes the whole gauge cluster (speedometer, tachometer, etc). I would recommend used because:They seldom fail, so a used one will work fineThere are a ton of Miatas that are parted out all the time, you may be able to find one with an odometer reading similar to yours, which reduces problems with smog or insurance claimsThe cost of these used is SIGNIFICANTLY less than buying newPlease see Related Links below for friendly, reputable used Miata parts dealersYou can also search on Ebay for "Mazda Miata Cluster"Note that you can purchase 1999 or 2000 year clusters to fit your carReplacing the cluster is very easy, and only takes a gentle hand. It is literally held in with 3 plugs, other than the cover that is simply pulled off. Please review the Related Links section for additional details regarding instrument cluster removal.
