Strange for me to be asking a windscreen related question

But a mate asked me this eve if a 2003 FRS would have a the loom and terminals already fitted for a heated front screen. I was surprised as I don't remember doing an FRS that HASN'T had a heated front screen, but he insists there's no dash switch for the front, only the rear....

So we were wondering if the loom and terminals were already there for it, and would it be as simple as getting a switch and connector for the dash, and obviously the screen. Then just fit the screen and connect up beneath the scuttle, and pull out the blanking plate on the dash and plug the switch in to make it work?
