Do you mean the integrated speedo/rev cluster mounted on the steering column or the discreet units?
The Speedo is coded to the BCM, if its the centrally mounted instrument - the cluster is behind it. If you have the speedo "pod" on the steering colum, the instrument cluster is part of the chrono pack or satnav unit - so either way, you are into coding (and worse) if you change them out.
The steering wheel mounted speedo/rev counter units are not difficult to swap - no instrumentation control is in there - they are only "slave" display units. You do need to code them, however, as they wont display the correct warning lights etc if you just swap them.
What is it you are trying to achieve?
Hope that helps.....
