Good evening,. I have recently acquired a 2004 2.5 Xtype with only 53k miles. She is a lovely sedan but my steering wheel has the typical curl. I have seen many threads advising the newer wheels were compatible. My question is the car doesn't have multifunction at the moment,is there a wire harness already there? I understand a bit of programming may be needed to activate cruise control but before i buy the used new style multifunction wheel just wanted to know if the wiring will need an upgrade too. Sorry if this has been asked a million times before.
