XC90 Dashboard temperamental

[TomW]

Does anyone know if I can take out the dash from my about to be scrapped 2002 V70 standard petrol engine and put it in my 2003 T6. In my T6 the whole dashboard has been going down with nothing displayed. Indicators and windows are also down. It occasionally springs back to life. I've looked through the forum and this problem occurs mostly on the older cars and in the summer heat when the electrics behind the dash expand and contract.
If the dash is identical and interchangeable I could do it tomorrow instead of sending it off for repair. By installing the V70 dashboard is this going to upset any electrics in the T6.
My old V70 has logged 30k more miles than my T6 so if swapping it is successful will the higher mileage from my V70 then be displayed in the T6?
Sorry not expressing myself very well but hope not too confusing.
The clean shot is the T6 and the other from the V70.
Thanks
Tom
