2002t5 power seat module - is used ok?

[gundito]

I have a 2002 v70 t5.
Took it to the dealer to get the drivers seat repaired - it stopped moving about a year ago.

They diagnosed it as needing a new "power seat module", $881. They said a used part cannot be used as this module links the entire computer system and a used model cannot be reprogrammed.

I called and ordered a used part from Erie VoVo, only $135, who assured me that the used modules they sell would work and their was no need to reprogram it.

Before I install this used part, can anyone offer me any reassurance?
