I am interested in purchasing rally lights for my mini. They are daytime running lights that attach to the grill.

Installing looks easy, however getting them to work may seem more difficult.
Who has installed these before and how difficult is it to hook up the electrical?
Where will the electrical wires hook in to?
Will I have to hook the car up to a computer so it recognize new lights?
I am sure that the lights will come with instructions, but I dont want to by them and find out that is more of a pain than I thought. So this is a perfect place to get feed back before I buy.
Thanks
