all moden stereos have the same connections, and will plug right into a MK2 just as long as no-one has butchered your wiring loom. only thing is the live & ign live wires on the MK2 are the opposite way round on MK2, but most stereos have bullet connectors so you can swap these over. also, most mk2s from the factory didnt have an ign live feed, so you have to plug both ign live & live wires on the stereo to the live feed.
