I fit these all day long, remember the heated screen is earthed behind the interior light on later models (the ones with centre plug under the bonnet) with a bolt to chassis if you end up having to wire it in yourself. Any decent windscreen company should supply you with a heated screen even if yours isn't one as long as its thru insurance, just tell em theres one in it and if when he comes to fit it the fitter questions it just say it was made with one and someones put a cheap one in
