I got my normal screen on my old van replaced with a heated one when it cracked.......the wiring wasn't there on mine, a mate wired it up and it wasn't massive aggro. Mine already had a switch in the dash for a reversing alarm, so we just used that. I had the correct original switch from a breakers, but it's apparently not easy to use if you retrofit the heated screen, there's a timer etc. If you do it the way I did, you just need to remember to turn it off after 5 mins or so, otherwise the elements in the screen risk burning out. Mine was just 2 cables run via the fusebox through 2 30 amp fuses, one to each side of the screen, and an earth on each side, from memory, worked a treat.
