Winter is comming. I own a 2009 Legacy 3.0R automatic. I would like to install teh OEM remote starter kit that sould be prewired, but I cannot find the Subaru P/N any where. There are P/N for Impreza, Forester and 2010 Legacy, but nothing for 2009 3.0R. Is this part available? If yes, what is the good P/N?
