Speedo change

[trumpet30]

Owing to a cracked cover I am changing the speedo on my car (58 reg Zetec S. It has the digital centre that can display MPG, Radio station etc.

Having read the Haynes manual it says if I change the unit I have to have it set by Fords WDS diagnostic system.

Is this right or is there another way round it, also if I do have to have the Ford WDS bit how much does it cost any ideas?

Well i'm not sure about a Ford, but a mate of mine had a similar thing with his Saab and the reason was that the programming needs to tell the speedo what size wheels he had on for speedo calibration purposes. This involved the use of a Tech II diagnostic tool and 30 minutes labour charge.
