Is there any difference between a au1,2 or 3 dash cluster, because I have a set of different dial covers for an au1 xr dash but my au isn't an xr and I want to buy an xr dash

As far as i know the clusters are different between the standard series 1 and the series 2 falcons . not too sure about the xr's though but im sure the pin config is different . This web page has all the pin positions for the falcon clusters so look here documents.php?d=4

Ah ok thanks, I might just buy the one I think it is and if it isn't right il sell it
