Advice Neede For Changing Standard C Class Headlights With Xeons

I HAVE RECENTLY A CQUIRED SOME XEON HEADLIGHTS FOR MY MERC IVE HAD A LOOK AT FITTING THEM AND NOTICED THAT THE STANDARD LIGHTS HAVE ONE PLUG ON WERE THE XEON LIGHTS HAVE TWO PLUG POINTS. WHEN IVE HAD A LOOK AT THE ONE PLUG I HAVE ON THE STANDARD LIGHTS THE WIRING LOOM IS THE SAME AND LOOKS LIKE IT WILL FIT THE XEON. WILL THE LIGHTS WORK OFF THE ONE PLUG? DO I HAVE TO CHANGE THE WIRING LOOM? IS THERE SOME SORT OF KIT I NEED? ALSO READ ON ANOTHER FORUM THAT I MIGHT HAVE TO GET THE COMPUTER CHANGED TO XEON FITTING IS THIS TRUE IS IT EXPENSIVE? THANKS IN ADVANCE:thumbsup:
