If your car is pre-wired then it should work perfectly (plug in harness under rear seat next to battery), if not then you probably will have to wire it in yourself. I wouldnt get the BMW one anyway, first off for that price you can get one with alot more features. I got a crimstopper one for bout 70 bucks and its real nice it was spliced thru the prewired connector. I think the only advantage with the BMW one is that you get the double lock feature, besides that mine has the window breaking and starter disable and all those other goodies.
