MY 05 facelift 3 door

My first question. My wife and I have now both got MY05 3 door freelanders BUT she has an SE and I have the XE. hence I am trying to uprate my lowly XE machine to her spec as far as I can. Powerfold mirrors is the next thing to look at and my question is - assuming my XE has the same harness then would all I need to do is replace the mirror switch, get a relay for the powerfold motor and Bob's your uncle. OR can I not assume that the mirrors I have on the XE are powerfold versions and would therefotre need to get some as well ?.
