peugeot 407 electric seat upgrade

[xantiaman1]

hi I have the opportunity to purchase a full set of electric seats for my 407 which has manual adjustable seats..Im not worried about the heated part I just want the seat to go back and forth etc.I have previously done this swap on a vauxhall I had a few years ago and it was just a case of identifying the live and earth but Im not sure about the 407 as this is the age of ecu's etc.any ideas?
